This is one if not the most informative videos on classic car frames, components, and most importantly the “why”. Really nice job fellas and thank you on behalf of everyone that learns from your shared experience.
Just a 48 year old enthusiast here that loves to see how it all goes together. What I really enjoyed on this video was some of the theory behind why you set it up the way you do. Makes sense to me. Other guys are just slapping parts together without that engineering mind. It’s the why that makes the what work. Great job. Algorithm directed me here. I had the opportunity several years ago to have a private Saturday tour of the Detroit Speed Shop and was amazed at the engineering that goes into their stuff. I’m happy to see you incorporate the same if not more degree of engineering in your entire build.
I'm an engineer working on trying to get into the hot-rod chassis industry and I gott say, this was very informative. Love this type of content! Thanks a bunch for sharing!
He really doesn't. He talks confidently and seems like he knows what he's talking about, but he is clearly full of crap if you actually know about suspension. His explanation of caster is laughable.
This is one of the most informative explanations on steering geometry I've heard. I took Auto Mechanics in high school, which seems like 100 years ago now, and I've read and thought about, as well as noticed, SOME of that over the years. This was definitely more informed and concise than all I had come up with. And you guys are actually doing it. Hats off to y'all, keep this stuff up and I'll definitely be watching more.
See so many hot rod chassis built with a panhard bar placed wherever it 'looks good', or watts linkage used 'cause its better' with no mention of roll center! Great to see some sound theory going into a quality build!
Regarding the caster angle - the primary reason that engineers reduced the caster angle in pre-70s cars was because it reduced steering effort when you had a manual steering box. It also caused the cars to become unstable at higher speeds creating a condition that slowed the cars down, but the primary reason for it was steering effort. Parallel parking a manual steering car was difficult, so reducing the return-to-center tendency made them easier to steer by reducing the caster to almost zero. Once power steering came into common use the steering caster was increased, but not by much initially. It took them a while to discover that increasing the caster also greatly increased the stability at high speed (even with worn out components), and in addition it helped anti-dive under hard braking. The anti-dive started to be important because disk brakes came into common use at the same time, which created far more braking force in the front end. The anti-dive was more important in the motorcycle world because heavy brake force really caused much more "dive" at the front wheel. This caused strange handling characteristics, especially when racing - so anti-dive started showing up on production bikes in the early 70s. Anti-dive then started showing up in production cars (like the Mustang II suspension) a little bit later.
@wackowacko8931 You are absolutely spot on. One other thing about positive caster that I like is how it promotes negative camber on the outside tire so that the tread stays flatter on the ground during hard cornering. They mentioned how a low panhard bar mount keeps roll centers low but its not the only thing that dictates rear roll center height, all of the rear suspension mounting points factor into roll center height. I was always concerned for guys that ran the wishbone on drag cars above the rear end housing vs below the housing. There are enough door cars out there going 230mph plus to prove that altering the height of the wishbone alone by 13"-14" is not as big of an issue as what I initially thought it was.
First you say caster makes the car unstable at high speed and later you say it makes it more stable? Also, a brake drum, can provide more braking power, but not after repeated brake applications? A brake discs requires more force to operate, in comparison to a brake drum?
Intro is trash. They cut before they say the important part. They are purposefully wasting your time. DONT PUT PARTS INTO THE VIDEO DESIGNED TO BE SKIPPED
Although, I may never be privileged to use any of the info I’ve learned here today it does in fact give me a proper perspective. This is like watching the process of a painter. True artisans. Thank you for the privilege.
I love the engineering and quality of the fabrication on this. Also the most concise and accurate description of how to engineer bump steer out of your suspension.
I really enjoyed your video. This is the first one of yours I ran across. Well done. Back in the 1980's, me and a friend ran a couple of Opel GT's on the autocross circuit. We made all our suspension bushings out of delrin. A great material. Thank you for the great information.
Awesome video - I really like the explanation of how things work, and why you are doing it the way you are. Your design, fabrication, and assembly all look to be top notch, as is your attention to detail. Edit to add - If I win the lottery, I'm bringing you my '64 Riveria.
I’m an old man I have reversed engineered many things to mechanically and electrically due to problematic systems anything from the Chrysler leanburg system back in the late 70s to caterpillar diesel 120 pin ECM‘s. I won’t even get into the mechanical aspects of other things. I absolutely love your thought process on your frame. I’m assuming you’re probably going to Powdercoat the frame. I just watched a video where the powder coated a 59 El Camino from the firewall back and honestly, it looked fantastic. I believe that was also in California. I think a company called Primo did it? I just subscribed to your page because of walking this video. Fantastic work guys. I applaud you.
You should consider the Terry Satchell designed Truck Arm Satchell Link. Specifically designed for NASCAR Winston Cup Road Course/Road Race use. Fully triangulated it has no need for Panhard or Watts link. It also is very stable at high speed and nimble at low speeds. Generally the Truck arms are self explanatory and the upper arms are shorter, above the axle and parallel and connected directly above the axle mounts for truck arms. He also designed a very similar system for use in Desert Racing particularly the Baja 500 and 1000.
Great video. I love suspension geometry… I built a frame for my Coyote swapped 1950 Ford Sedan. 4Link with Mustang II front suspension. I reinforced the rockers and kinda did the unibody style. I’m using coilovers and running 4” of ground clearance.
I commend you on your vision and dedication. Each one is different and you understand and see how it all works together. Thank you for sharing and blowing my mind. Long ago I used to work in this arena but life took me a different direction. Thank you for sharing.
Great video, great build, great suspension design. FYI from an old timer, 55mph didn't come around until the '70s, before that most highways were 70mph. And States like Nevada and Montana didn't even care how fast you went on the open roads!
So, I’ve got a 64 with full Ride Tech front, I’m having some issues and this is fantastic to watch and reinforce what I’m saying to my fab guy, I’d love to Unibody mine… Thank you for sharing your knowledge Good luck
I've always wanted to try my hand at building my own tube frame chassis. Some of the sheet metal fabrication and shaping for hotrods that I watch on the youpoop seems like magic. Thanks fro sharing.
I enjoyed and did learn more as i am doing a bit of research for a possible build. Paul you seem to be a chill genuine guy and for that I thank you. Brandon your craft shows to be above standard. hope to and looking to speak with you soon.
This is fantastic video. Thank you so much for sharing this information. I need to rebuild the front end of my Duramax and you helped answer a question about starting an alignment from scratch after a full rebuild. I really like the idea of Delrin bushings. Someday I'd like to build a full custom chassis for my truck gave me some ideas.
Wow Thank You for this video!!! This Really reinforces my ideas behind the chassis I'm building for a friends S-10, Although I used the original front suspension from the firewall back is fabricated. It will also be unibody in the cab. It will have a full air ride suspension and a 4 link rear suspension. Again Thankyou for this. !!!!!!!!
Very informative video, and it highlights your attention to detail. I'm pretty sure I'll never be able to afford one of your builds, but this info helps us guys that will end up building our own.
This kind of information is out there but most people don’t understand it anyway . Have built several chassis since 70’s , the first book I read on suspension was Herb Adam’s , what a great place to start. ❤❤ I subscribed to watch future information ❤❤
I didn’t even realize that it was a convertible impala. Looked like a K5 with a trunk. But that is a very nice detailed vehicle. Can’t wait to see more videos of it during the build process.
Awesome vid, great info, always hard to find info on how to design your own front end with things like where to start, where everything should be mounted and setup, roll centers, etc so much appreciated for the info you's have shared in the vid 👍
Man! I really appreciate this video! I have been so set on RS for my next build. But I really like the genuine spirit and openness these guys have. I just have to figure out what I want to build. My ‘37 GMC COE OR….❤❤❤❤
Love all the work and agree with everything you covered…one problem stood out lol… next time hide the seam of the frame tubing to the inside, it doesn’t cover with paint or powder! 😜😊
It’s kinda funny how long it took the custom car builders to really start paying attention to standard concepts like setting bump steer, anti dive, roll centers, proper caster / camber settings. Still fairly primitive in understanding and implementation. I mean farmers have learned to grasp it in dirt racing. I see a lot of builders failing to understand dynamic caster camber curves, pin inclination, motion arm ratios, dynamic roll corners and weight transfer. Nascar and racers use panhard bars because we leverage the dynamic roll center changes as well as the loading and unloading of the RR. Something critical on circle track racing. 1/8 lateral movement is actually a lot on a street car going straight as well as the four bar locations. Also there’s nearly no/ zero net gain with bump steer. Adding scrub for stability isn’t really a logical or factual concept and is just an old fairy tail. The issue is that it’s nearly impossible to have a zero bump on both rebound and compression which is especially true for any offset style chassis. The chassis shown in the video has very little caster gain but this is something 99% of chassis experts fail to understand. I’m betting these guys never bumped that wheel and plotted the caster camber curves.
We use 1.25" od x .120 wall on the lower and 1.0" x .120 on the upper. Only down side is the inside tire moves out more at the top with added caster. This could cause interference with the fender.
I'm very interested to see an NVH evaluation of this when it's complete. These old cars rely on a lot of frame twist, soft bushings, and tire sidewall to keep them comfortable. That's all gone now. I hope it works!
Fantastic video. I love seeing these techniques. I've always been curious to see how these methods can be applied in other applications like imports or hell even an EV since the box frame looks like it could hold a battery pack like a skateboard platform on a production EV does.
Interesting to see technology on frame, chassis, and body pan…. That you are using….. and is still proving itself from many years ago…….and started with a man named Dr. Fergon Porsche and how his floor pan frame rail, incorporated design, and a few years later independent suspension travel,and linked bars are still important today….
@12:31 Lowering the roll center creates more body roll. @20:19 Trail is what self-centers the wheel. Weight jacking depends on scrub radius. @21:25 Caster is unrelated to anti-dive.
1. Lowering the roll center in our case does in theory create more body roll but it takes out the jacking effect which raises the center of gravity. This will essentially give us more grip in a corner. 2. Correct. Trail is created by the caster angle. Scrub also can help to self center. 3. Correct. However, the angle of the upper control arm increases caster as it is bumped which can help stabilize steering during hard braking and diving especially braking in a turn.
As a you g filipino who plans to build his own owners type jeep some day, this video is very important specially for the type of application I want to place my jeep in.
I love suspension and chassis stuff, great video! I do question the slots and holes you put in the K-member though. If that car gets driven much, those are just begging to pick up all sorts of dirt, sludge, debris, etc from the road and in turn holding moisture in those spots down the line.
The problem with Polyurethane lower arm bushes, only applies if the spring seat is on the lower arm, making it constantly loaded. If you are running a MacPherson strut type situation, then they seem to last much longer?
Appreciate the info. I'm gonna build a mandrel bend 2x4 frame for my 67 c10. Thought about making the whole thing uni body. I dont see a purpose of making the cab and bed removable.
Great video, about those spindles: how much pin inclination / KPI are those built with? And what will Your scrub radius bee with the rims/tires You choos?
We are sure there could be some discussion over this one! We single bevel and butt weld our joints using GTAW (Tig). We make sure that our joints are mitered so that the weld is actually much larger than the cross sectional area of the tube itself. A full penetration weld is always stronger than the base material. Our guys are make certifiable welds per AWS so we feel very confident about them. However, if you do not feel confident about your weld quality a backing plate or an additional plate is not a bad idea.
@@oldanvilspeedshop Awesome, thanks for the reply! I'm going to be extra cautious and add some inner plates to my frame build. My welding is just ok so I'll spend a little extra time smoothing some plug welds just for peace of mind.
Spent 50 years in the automotive/heavy truck industry, mostly on the manufacturing side. I am still waiting to hear about any engineering. Saw some fabricating, got a sales talk, saw some creative use of existing technology that others engineered, a clumsy and sophomoric description of caster, but nothing an engineer would be saying. I am not an engineer but at least I would want to know the section modulus and RBM of the frame (especially in the cross-sectional area you welded in the exhaust pass-through) as well as how you determined the final Ackerman Angle. Did you at least do a non-destructive stress coat test series? Again, I saw no engineering.
Great info! not enough people out there talking about how to properly build suspension. Too many universal kits and wherever it fits type of recommendations 🍻
This is one if not the most informative videos on classic car frames, components, and most importantly the “why”. Really nice job fellas and thank you on behalf of everyone that learns from your shared experience.

Nice to hear somebody who actually understands suspension dynamics and front end geometry. Beautiful execution, thanks for the "secrets".
He really doesn't. He talks confidently and seems like he knows what he's talking about, but he is clearly full of crap if you actually know about suspension. His explanation of caster is laughable.
Getting down to these details is what I love the most. These secrets could help us all build better and safer cars. Thanks for sharing!

Very nice work guys, CAD has been a huge benefit along with testing new things. This channel will do very well...
I have been making my own bushing out of Delrin for years. You are very correct on using this material.
Having a chassis built for my 59 and this was really helpful to listen to and get a glimpse to your process. Thank you.

Your attention to detail is so impressive. Even the aesthetic of your shop is well thought out. Makes you want to get to work.
Another awesome well produced video. Thanks for sharing your knowledge Paul.
Thanks, we appreciate the support!

"Kind of like a shopping cart.. That's why they call them casters". Dude, I never made the connection between caster and casters before. TY! LOL
Once you hear it, it just clicks huh?!
Caster(s) function as if the wheel is being pulled not pushed. Now it makes even more sense.
Awesome vid, great info, always hard to find info on how to design your own front end with things like where to start, where everything should be mounted and setup, roll centers, etc so much appreciated for the info you's have shared in the vid 👍

I have a 32 ford cab I have for myself but nowhere to do it until I move out and would love to have this as a reference
@12:31 Lowering the roll center creates more body roll.
@20:19 Trail is what self-centers the wheel. Weight jacking depends on scrub radius.
@21:25 Caster is unrelated to anti-dive.
1. Lowering the roll center in our case does in theory create more body roll but it takes out the jacking effect which raises the center of gravity. This will essentially give us more grip in a corner.
2. Correct. Trail is created by the caster angle. Scrub also can help to self center.
3. Correct. However, the angle of the upper control arm increases caster as it is bumped which can help stabilize steering during hard braking and diving especially braking in a turn.
Thanks for sharing, really good info to know.
Also, I dig your glasses.
As a you g filipino who plans to build his own owners type jeep some day, this video is very important specially for the type of application I want to place my jeep in.
Super informative. Thanks. Appreciate you both.
I had a 62 but sold it years ago.. Great work
Shave the firewall. Add side panels. To hide the door hinges 5 or 6 inches on the side. Reinforce the fenders and remove the inner fender.
So fun to listen to you guys ❤
Lots of knowledge bombs getting dropped in this video. Great work and great info!
That was the idea! We’re glad you found it helpful.
The rendering looks amazing!
Yes finally somebody that talks Bump Steer
I don't know much, but it is beautiful. Thank you 😊
We appreciate you watching and glad you liked it
What did I learn?....I learned that I need to stop up your shop and talk to you guys about a custom chassis. That's what I learned.
Come on by! Our address, contact info, etc. is on our website: oldanvilspeedshop.com
I love suspension and chassis stuff, great video! I do question the slots and holes you put in the K-member though. If that car gets driven much, those are just begging to pick up all sorts of dirt, sludge, debris, etc from the road and in turn holding moisture in those spots down the line.
Tire size, thank you, thats where Ill start with my build!
The problem with Polyurethane lower arm bushes, only applies if the spring seat is on the lower arm, making it constantly loaded. If you are running a MacPherson strut type situation, then they seem to last much longer?
Appreciate the info. I'm gonna build a mandrel bend 2x4 frame for my 67 c10. Thought about making the whole thing uni body. I dont see a purpose of making the cab and bed removable.
Great video, about those spindles: how much pin inclination / KPI are those built with? And what will Your scrub radius bee with the rims/tires You choos?
Great video! Care to share any insight on how you make your z connection? Just butt weld or do you add inner fish plates and rossett weld?
We are sure there could be some discussion over this one! We single bevel and butt weld our joints using GTAW (Tig). We make sure that our joints are mitered so that the weld is actually much larger than the cross sectional area of the tube itself. A full penetration weld is always stronger than the base material. Our guys are make certifiable welds per AWS so we feel very confident about them. However, if you do not feel confident about your weld quality a backing plate or an additional plate is not a bad idea.
@@oldanvilspeedshop Awesome, thanks for the reply! I'm going to be extra cautious and add some inner plates to my frame build. My welding is just ok so I'll spend a little extra time smoothing some plug welds just for peace of mind.
Spent 50 years in the automotive/heavy truck industry, mostly on the manufacturing side. I am still waiting to hear about any engineering. Saw some fabricating, got a sales talk, saw some creative use of existing technology that others engineered, a clumsy and sophomoric description of caster, but nothing an engineer would be saying. I am not an engineer but at least I would want to know the section modulus and RBM of the frame (especially in the cross-sectional area you welded in the exhaust pass-through) as well as how you determined the final Ackerman Angle. Did you at least do a non-destructive stress coat test series? Again, I saw no engineering.
Great info! not enough people out there talking about how to properly build suspension. Too many universal kits and wherever it fits type of recommendations 🍻
