This is 'the' BEST video on suspension geometry...Thanks a lot ! (I worked as an automotive diagnostic equipment service engineer for years, and i know what i'm talking about) Please do videos like this and don't worry about the length of the video... its good info...
This is the best video about suspension geometry I've seen so far. Really helpful how you actually showed the effects of different adjustments in geometry!
This is really good stuff. Steering/suspension geometry is one of the hardest things for me to understand conceptually as someone with no real practical automotive or engineering experience, just an interest. I'd love to build a little sports car like your own someday, it seems so cost effective for the amount of thrill you get.
Just check miata forums, craigslist and autotrader. A miata with aftermarket suspension parts and wide wheels/tires can be had for $5k on up. The most economic, reliable fun you can have on four wheels. If you can DIY even replacement engines and trans are dirt cheap.
You did way more than just your homework! Your explainations combined with your geometry animations make a complex and mostly "hidden" part of your car unterstandable for every level of car enthusiast!
Absolutely amazing explanation. Will definitely send this video the next time a friend doesn't get camber/caster/toe/etc so I don't have to give lectures 😂
Man you are a great teacher; you can take a learner from zero to pro. That's an incredible skill that not much teachers have. Your explanation is so clear and simple that a beginner can understand, and your understanding and fluency is so good even going into advanced concepts. I'm not even gonna start talking about the great animation and the amount of work and dedication you put in that, but man that's a master piece. I'd like to thank you on behalf of the world!
Hi. What software is used to do this animation? I want to star a website/blog focused on car tech and think it might be usefull to explain a few things.
Yeah ! Great diagrams and explanations. I just went to a motorcycle meeting, and I have a background in cycling. I owned a few suspension bikes, and could not get them working properly. I previously decided to invest in a really good BMX, that's all. But, looking at the motorcycles. It was odd to see. Large rear tyres, tyres with an odd shape, and weird orientation of the springs. I read today motorcycles have 57 x more accidents than cars ! Yet, they're a lot cheaper. I might save money through investing in some skill hopefully.
Just came up in my feed as "recommended" Glad I checked it out. I've learned more about terminology and the mechanics of steering in this one video than anything else I've watched. New subscriber!
It can cause squirm. There would be no force on the tires pulling them one way so if you happen to have play in your tie rods the tires will try to move around one way or the other. With some scrub radius that doesn't happen because there's always some force holding the tires one way
Hi, Amazing Video It looks like you have done Anything that has to do with all parts of suspension. I am working on a 55 year old TR6 with some archaic designed parts. I am looking to do some spirited driving, ie autocross. Of the aftermarket “kits” ie mustang II, or others, are there any that stand out as being better? The car weighs about 2500 lbs. I have an aftermarket full square tube frame, so cutting off a frame section are replacing it is not a concern. I am hoping this opens up many suggested choices. Thanks in advance. And yes please to more videos like this. You made the explanation much better than some other videos I have watched. KJ
I'm building a hybrid cross kart slash , go kart / something lol. Anyway fully independent front and rear suspension . . Double wishbone rear end. I didn't pass a single mat class past 7th grade so obviously I can't to math lol. Anyhow I designed every aspect of my suspension using 4 ft cardboard sheets, thumb tacs, string lines, and 1 to 1 mock ups of my control arms and spindles. Worked amazingly well with no math. Moral of the story pay attention in school 😂😂
Say I've got 2 sets of wheels, one with a high scrub radius and one with a low scrub radius. lets say I have a very light car with a "racey" caster of 3 deg. Could I change the wheels SR effectively giving me a different caster "feeling" without actually changing caster? One set of wheels for on street/ heavy steering but stable and the other for autocross/ easy fast steering but twitchy?
Great work. Very clear. I definitely learned much from this vid. This is the best explanation of suspension that I've seen. I'm not stupid but I have struggled with some of these concepts in the past and watching this I realized it's because in the past I was presented with the intended result of a particular modification, but not "why" or "how". You nailed it. Don't worry about the length; I appreciate that you're not "dumbing it down" .Complex topics take time. I'm happy that I've found someone who understands it to this level... AND has the ability to communicate it. Thanks so much for the quality content. Looking forward to watching all your videos. How did you become so knowledgeable about suspension ?
" SIMPLICITY IS THE ULTIMATE LEVEL OF COMPLEXITY " Leonardo DaVinci. And here is a good example of how to explain something well and clear of a topic that is a mix of Art and Science
This is a fantastic video. I've been racing for decades, and have read many books on suspension geometry, but do not consider myself a master of the topic. You are, and this video brought it together in a way I haven't found elsewhere. Great job. I appreciate your efforts.
how do you figure out where exactly to put each bar? i'm trying to fully simulate a car's powertrain in unreal engine and i cannot find any guide on making suspension/steering geometry (apart from an old solution to ackermann steering.) is there a guide you know of? thanks.
I have a 1997 F150 which I am wanting to lower and I am having a problem deciding if I need a drop spindle or a drop lower control arm how do I know which is best for the geometry
Hey I have a Clio 172 RS and it tends to understeer more with spacers.... I really don't know how it relates on an FWD small hatch, front heavy, scrub radius don't effect cornering directly does it?
You feed information at a very fast rate. The inflection in your voice (or lack there of) makes picking up on key points more difficult to pickup on. The topic is very dense. You obviously have a PhD level understanding of it. Would slightly slowing your cadence help? For old farts like me the answer is yes. Maybe it’s my problem. Lol.
What they said. Yup. Now I have a question. Nobody is talking about the effect camber has on the contact patch relative to steering pull and toe effect in combination. If I have negative camber and 0 toe on one side of the front, but positive camber and 0 toe on the other, which way does the car pull, and why? What tricks can be used in equally cambered axles, like toe adjustment, can be made to cancel the contact patch squirm/pull from camber? Meaning: With a modest amount of negative camber that cannot be adjusted (some car companies) what amount of toe is used to compensate for the contact patch deformation, if any? I have an '04 Acura TL that my book says has fixed camber all the way around. The rear toe is noticeable when viewed from front or rear. Is the amount of toe I am seeing there to compensate for that camber, or is it merely to mitigate terminal oversteer? The car is pretty nimble but not nearly as much as my brother's Ford Focus. That thing is a gymnast!
I've a problem in my Kia multilink. My car feel too hard (solid)and at the same time too soft (shake side to side). I noticed a little sag in the rear and also a little negative camber. The rear left wheel has more sag and more negative camber. I change 4 shocks and 4 springs. I bought eibach springs -10mm because I think the oem was too softer or garbage. After this swap the car feel only little better for a month and now a rock like before... Now I change the upper links arm (not the arm that can modify the toe) because the silent blocks look a little off cender and it could be the cause of the negative camber. The cornerig and shock absorbing improved but only for a week, now stiff rock solid again... The only improvement is the the car don't shake like hell when encounter another vehicle in the other side ( a front left shock absorber was defective) I don't understand what's wrong with this car. I read about many different kia or hyundai with the same insolvable issue. I don't understand why my rear left wheel sit lower than the rear right also with new springs and shocks. Are not the springs that lift the car or multilik have some trick to lift the car ? I don't understand why I feel all little road irregularities or little pot holes like if the car fall in a huge road sinkhole...
Obviously the statements in this video are extremely General and don't go into technical info such as Tire design & dynamics that require various camber alignment to optimize Tire performance.. .
I found myself watching this video and learning things just because I suck at racing video games. At least now I know how to set up my car properly, so if I keep sucking, I know it's the drivers fault.
I was really hoping you'd get around to suspension setups with 4 ball joints like you have pictured at 0:45. I'm having a hard time wrapping my head around that one. Best i can figure it allows for some tuning of how KPI, and Caster with steering angle.
When l was working on Mercedes in the 80s l noticed quite big kpi camber. I didn't know much back then but my initial impression was that they knew what they where doing, by helping the car into the corner......
can you do a video ( or do you know of a video ) that goes over how to setup a car ? ex : if your car is a FR layout and has a balanced handling characteristics and you want to add more under / over steer etc ? like how would the car react if you added more dampening to the coilovers in the front vs the rear and vice versa. ( leaving the front where its at and only adjusting the rear and vice versa vs front going full soft while going full still in rear and vice versa etc ) i cant seem to find any videos discussing this topic ( and i know it varies platform to platform ) but just in a general sense. maybe FF vs FR vs MR vs AWD etc like , if you did one setup change on FF layout it would be complete opposite reaction if you did same setup changes on FR etc
I don't know why but everybody says that the caster angle keeps your wheel straight and that it's like shopping cart. It's not. The caster angle is the angular displacement of the steering axis from the vertical axis. Shopping cart has the 0 caster angle.
These videos are very useful. I am designing my own suspension system for a single seater and your videos have helped a lot. Could you tell me which software you use to show the changes in the angles in bump/droop and steer? Thanks.
Hey. I got a question for ya. My friend got a wide body kit for his gt86, and he installed a set of 25mm spacer for it. After that, the car's handling characteristic completely changed. This is expected, but something I don't understand is that why the steering wheel no longer able to follow the drift when the car start to silde? What I mean is that when I try to drift it, I had to purposely turn the wheel to the opposite way to catch the drift. Before adding the spacer, I can just let go the steering and catch it at the right moment to finish the drift.
A+ for animation and the explanations of the physics behind suspension and steering phenomena. F for narration. I can’t dispute the science behind this video but the narrator have no delivery skills. This video needs to have a different narrator but keep all the existing science data including the animations. Good luck, thanks for the effort.
I'm trying to figure out what I need to adjust to correct the steering and suspension geometry after having to add 16mm of positive offset to both wheels (the fronts needed spacers for the brake calipers and the rears came with an incorrect neutral offset and I paid too much to get them both made again!).
Very good video. A shame you have a tendency to speak a little fast and gloss over technical parts which are quite complex for beginners. But still a lot of good insights for setting the car up.
Thanks for this graphic depiction of what our wheels really do when we turn our steering wheel! Two questions: If someone told you you could have as much SAI or Caster angle as you desired, but could not have both, which would you design into your suspension, and why? Secondly: My particular car has Zero Scrub Radiu. I have read, from numerous sources, that Positive SR can make the steering heavier. I WANT heavier steering! I CRAVE heavy steering, compared to the wishy washy steering in most 2010 or later automobiles. So would adding modest spacers to my front wheels, to generate this positive SR, be okay?
You did awesome job in this video. I study suspension for years and one or two things didn't know. Keep up the good work and thank you for sharing your precious knowledge 👍🚗
Do you always want your scrubradius to be minimized? because scrubradius also increases the feel in your steering in long turns right? the downside on a large scrubradius is indeed de toe-in or toe-out effect and the huge forces on your steeringrods. What do you thinks about this?
i am going to use this knowledge to custom make a new front suspension on a 60s f100 lol not completely from scratch but see if i can fabricate to make more modern parts work with a few older parts
This is 'the' BEST video on suspension geometry...Thanks a lot ! (I worked as an automotive diagnostic equipment service engineer for years, and i know what i'm talking about) Please do videos like this and don't worry about the length of the video... its good info...
It's kinda funny that he seems to almost apologise for the video being too informative.. ;-)
totally agree!!!
He should get an editor and clip the video into pieces. 10 min videos are optimized for viewer attention and ad revenue!!
This is the best video about suspension geometry I've seen so far. Really helpful how you actually showed the effects of different adjustments in geometry!
01:20 Camber
05:42 Toe
09:21 Scrub Radius
10:44 KPI (King Pin Inclination)
15:12 Caster
what software is this ?
This is really good stuff. Steering/suspension geometry is one of the hardest things for me to understand conceptually as someone with no real practical automotive or engineering experience, just an interest. I'd love to build a little sports car like your own someday, it seems so cost effective for the amount of thrill you get.
After all of the money you spend in custom parts the most cost effective option is a used Miata. Expect to spend at least $20,000.
Just check miata forums, craigslist and autotrader. A miata with aftermarket suspension parts and wide wheels/tires can be had for $5k on up. The most economic, reliable fun you can have on four wheels. If you can DIY even replacement engines and trans are dirt cheap.
Complicated engineering behind simple looking things.
You did way more than just your homework! Your explainations combined with your geometry animations make a complex and mostly "hidden" part of your car unterstandable for every level of car enthusiast!
Super helpful, incredible job putting this video/guide together!
I like the format and the way you explain, it's awesome, keep it up!
Absolutely amazing explanation. Will definitely send this video the next time a friend doesn't get camber/caster/toe/etc so I don't have to give lectures 😂
What software are you using to model the geometry?
Looks like it's Cinema 4D.
Why does it look like Lotus to me?
this video is the best video on youtube that covers this topic, please keep up the good work
Man you are a great teacher; you can take a learner from zero to pro. That's an incredible skill that not much teachers have. Your explanation is so clear and simple that a beginner can understand, and your understanding and fluency is so good even going into advanced concepts.

Hi. What software is used to do this animation?
I want to star a website/blog focused on car tech and think it might be usefull to explain a few things.
Blender Animation software
Fantastic video! 3d visualisation makes very easy to grasp the concepts
thank for sharing, is it possible to include the pros & cons between mcpherson & multilink geometry as well ? Cheers
Sure, I'll do that in the next one
Yeah ! Great diagrams and explanations. I just went to a motorcycle meeting, and I have a background in cycling. I owned a few suspension bikes, and could not get them working properly. I previously decided to invest in a really good BMX, that's all.
But, looking at the motorcycles. It was odd to see. Large rear tyres, tyres with an odd shape, and weird orientation of the springs.
I read today motorcycles have 57 x more accidents than cars !
Yet, they're a lot cheaper. I might save money through investing in some skill hopefully.
Oh wOw, now there is an video who can finally describe the funktion & reasons, clear & understandable shown
THX U Berry verry much 🙏🙏🙏
Nice work buddy.can you please give the source of the material it would really help for further analysis
Nice... really explanatory. Please which software did you use for the modelling and animation?
Very educational and easy to understans. Love your work
you can make 2 hour videos man no problem, podcast genereation!! =D
Simply awesome!! Great work man, keep it up
It is Cinema4D?
Mate, slow down and speak clearly! You can even make three or four parts of this video, but it's not a big deal until everybody can understand you! ;)
Lol try watching at .75 or .5 speed
Amazing in depth video! What software is this?
How did you made this video .. on which software ?
I dug further down in the comments and he mentions that he used Autodesk 3ds Max for the CAD portion
The BEST Teacher! Wow, I'd no idea about any of these topics 20 mins ago and I feel I've learned something very important... Great job!
Perfect keep going.
Thank you very much for what you do, I am impressed!
Does the KPA parameter depend on the outer diameter of the wheel?
Just came up in my feed as "recommended"
Glad I checked it out. I've learned more about terminology and the mechanics of steering in this one video than anything else I've watched. New subscriber!
Why can the center of the contact patch and steering axis be in the same point . just wondering !
It can cause squirm. There would be no force on the tires pulling them one way so if you happen to have play in your tie rods the tires will try to move around one way or the other. With some scrub radius that doesn't happen because there's always some force holding the tires one way
what software is this?
this dude makes me think about cars totally differently...i love it!
Very very wonderful
Finally I can learn in an easy to understand way this stuff! Super impressive!
Very well explained. Best I have seen on RUclips. Thanks.
Now I have a much better idea on setting my 991GT3 before a race....on ACC, that is.

Obviously the statements in this video are extremely General and don't go into technical info such as Tire design & dynamics that require various camber alignment to optimize Tire performance.. .
Would this steering geometry improve if it had 5 degrees less KPI, and if so, how much and in what ways?
I found myself watching this video and learning things just because I suck at racing video games. At least now I know how to set up my car properly, so if I keep sucking, I know it's the drivers fault.
yes it is helpful.....very......
But for me as a non english guy your voice is a bit hard to unterstand, but great videos!!👍👍👍
It was really informative and interesting! THANKS TO YOU...!
Really please actually try to spit out a VEEEEE sound. Last I checked there's no English language word that is "wertical" please try harder 🧐😐😙
I was really hoping you'd get around to suspension setups with 4 ball joints like you have pictured at 0:45. I'm having a hard time wrapping my head around that one. Best i can figure it allows for some tuning of how KPI, and Caster with steering angle.

can you do a video ( or do you know of a video ) that goes over how to setup a car ?
ex : if your car is a FR layout and has a balanced handling characteristics and you want to add more under / over steer etc ?
like how would the car react if you added more dampening to the coilovers in the front vs the rear and vice versa. ( leaving the front where its at and only adjusting the rear and vice versa vs front going full soft while going full still in rear and vice versa etc )
i cant seem to find any videos discussing this topic ( and i know it varies platform to platform ) but just in a general sense.
maybe FF vs FR vs MR vs AWD etc
like , if you did one setup change on FF layout it would be complete opposite reaction if you did same setup changes on FR etc
Ohhh my goodness!! Thank you for this video. You are amazing man
this video was very very helpful , i am working on a awd 2jz tube chassis and this is my biggest concern , I am subscribing for sure.
I don't know why but everybody says that the caster angle keeps your wheel straight and that it's like shopping cart. It's not. The caster angle is the angular displacement of the steering axis from the vertical axis. Shopping cart has the 0 caster angle.

Please slow your speech down. You speak English very, very well but very fast, too fast.
Please share the technical specs of the bike shock absorbers used in your E55 ASL project. Thank you.
Hey. I got a question for ya. My friend got a wide body kit for his gt86, and he installed a set of 25mm spacer for it. After that, the car's handling characteristic completely changed. This is expected, but something I don't understand is that why the steering wheel no longer able to follow the drift when the car start to silde? What I mean is that when I try to drift it, I had to purposely turn the wheel to the opposite way to catch the drift. Before adding the spacer, I can just let go the steering and catch it at the right moment to finish the drift.

What should be caster angle on a 6 inch lifted Dodge Ram 1500 4x4 (98)
Thank you for your efforts. I really appreciated it.
Im building a very advanced motorized soapbox in school next year and with the help of these awesome video's, mines gonna dominate the race!
Ok so negative is usually better for anything to do with suspension
Edit: except caster :)
I'm trying to figure out what I need to adjust to correct the steering and suspension geometry after having to add 16mm of positive offset to both wheels (the fronts needed spacers for the brake calipers and the rears came with an incorrect neutral offset and I paid too much to get them both made again!).
Amazing video. You're incredibly knowledgeable!
Very good video. A shame you have a tendency to speak a little fast and gloss over technical parts which are quite complex for beginners. But still a lot of good insights for setting the car up.
Thanks for this graphic depiction of what our wheels really do when we turn our steering wheel!
Two questions: If someone told you you could have as much SAI or Caster angle as you desired, but could not have both, which would you design into your suspension, and why?
Secondly: My particular car has Zero Scrub Radiu. I have read, from numerous sources, that Positive SR can make the steering heavier.
I WANT heavier steering! I CRAVE heavy steering, compared to the wishy washy steering in most 2010 or later automobiles.
So would adding modest spacers to my front wheels, to generate this positive SR, be okay?
Heavy steering rules!!
Great content! could you please let us know what software did you use for 3d modelling of this video?
It would be a great idea to open your mouth while speaking. Nose is far better for breathing than for speaking.
Excellent information, and exactly what ive been trying to find.
Thank you
do you have a patreon account? I'd like to donate
Ohhh thankkkk u for splitting it into two different videos. A single video would’ve been an overwhelming amount of information
Can't you use virtual pivots to get 0 degree KPI and good scrub radius then ? What would be the downsides of that ?
16:17 Amazing steering technique tho! I've never seen that before.
I like how im watching this as im about to build a gasser with a front straight axle syspension desighn from the 1800s
I would like to know more about the clip at 1:12 and 6:55 as it looks like a 6th gen Honda Civic cluster and 6th gen Honda Civic upper control arms
You did awesome job in this video. I study suspension for years and one or two things didn't know. Keep up the good work and thank you for sharing your precious knowledge 👍🚗
Mitsubishi Galant('96-'02) has a small negative castor.
Do you always want your scrubradius to be minimized? because scrubradius also increases the feel in your steering in long turns right? the downside on a large scrubradius is indeed de toe-in or toe-out effect and the huge forces on your steeringrods. What do you thinks about this?
i am going to use this knowledge to custom make a new front suspension on a 60s f100 lol not completely from scratch but see if i can fabricate to make more modern parts work with a few older parts
Good stuff. Wish I could get a decent alignment somewhere. Shops dont do anything but toe and call it good
5:29
this vid helped me big time!! keep posting vids that focus on the little things bruh
Excellent video and graphics that make it very clear what you are talking about.
