Thank you, these episodes were very helpful and comprehensive. Let me share you back a tip to make sure the steering wheel is dead-on center: place a bar in front of the steering wheel and let it rest over your windows rolled down (or clamshell, in your 1-seater). Then, tie the left and right spokes of the steering to the bar with belts/cinchs. Is also good to do the alignment with your weight inside, just as you did with corner balance. You may enjoy having a water dummy or ballast in the seat while you work all the parameters.
Excellent production Steve. That’s how I do it. Glad you put the mesh in the side pods. It will protect everything in them. Can’t wait for the on track shake down.
We have a multi car touring car team and did the same exact method to align the cars for many years. People can't believe that it is more accurate than expensive laser systems. We now use basically the same method but with hub stands which makes the job much quicker. Great job on the video and you really explained it well. Loved it!
The ever-best explanation I have seen in all my life. Thank you very much! BTW You're a very experienced race driver, not your age but your experience adjunsting your car, in this way you know what to expect from all adjustments, what works and what not.
Hi Steve, thanks so much for an excellent series of videos. I'm driving a Formula Vee in the South African Monopisto race series. I'm a complete novice and your videos have really pointed me in the right direction. Thanks 👍🏻
Happy to hear this Mark, and enjoy your formula V, its a great race car . I am sure you will enjoy it. Also talk to the others that have been driving for a while. They can give you good advice...
Hey Steve, Your videos are fantastic, easy to follow, and I love the theory and practical tips. Can you make a video on caster setup? There's a gap in practical explanations out there, and your teaching style is spot on. Cheers! Bert
I am fortunate to have a "4 Post lift and have adapted your type of set up to that. I use lengths of tubing that are somewhat longer than the spacing between the lift corner posts. I buy electrical conduit tubing; cheap and readily available in long lengths. At each post I use a short length of tubing of a somewhat larger diameter than the X-wise tubes held to the post by bungee cords stretched very tight. These support the X-wise tubes and can be easily adjusted for desired height. The X-wise tubes are marked same as yours and can be easily positioned by sliding in the larger pieces of tubing at each lift post. I tie a loop at each end of each of the strings and slip one end over the tube. I make the string longer than the distance between the front and back so I can wrap the other end over the tube and tension it with a Bungee cord attached to the string loop and the other end to to lift ramp, each side. This gives a very tight string for accurate measurements. I use a digital Vernier for measuring. On another subject I think I see that your car has a speedometer. I raced several different cars for many years and non had a speedometer. Everything was relative to engine revs. Sometimes it's a bit scary to see the speed and again, not really useful. As you approach the limiting speed for a given corner you will notice that the steering becomes less responsive, the car is telling you that it has very little more grip to give you. You do a great job.' Tom G.
great content and presentation as usual. If you put a couple of layers of newspaper under the front wheels the can slip easier when centering the steering wheel. Best wishes from Australia
Although toe affects on straight line stability, the final degree depends on the steering design, more specifically the ackerman. A lot of ackerman accepts more toe in until it starts to understeer, and less ackerman needs more toe out to make the car turn a corner. Also, when you are using the edge of your rim to as measuring point, make sure that edge is straight.
I use the string method but always measure to the flat part of the wheel just inside of where you are measuring, where the tyre bead sits - mainly that's important on steel wheels rather than alloys as you have. On steels, the rim edge can be a bit "wavy" and give bad readings when setting toe.
I like the simplicity of your rod setup...however. Although the lines are parallel the box may not(probably not) be square, which could lead to significant errors in measurement at this level. Squaring the box requires removing the car and measuring the diagonal corner of the box to verify they're equal. That is measure from right front to left rear and left front to right rear...Straighten the string and rods until all is equal and you're ready to go.
Hello, my name is Mike. I'm from the US and California. I really enjoy the detail in your videos. I was wondering did I miss the part on Castor as far as the alignment specs?
A great educational video (as usual :-) ) and a simple way of doing the alignment! Thanks! Just a brief thought and possibly a stupid question: How do you know that the front wheels are pointing straight ahead and the steering wheel is dead center before the adjustment? What I mean is ("I" is a wheel:-) ): "I" and "I", not "/" and "/", or "\" and "\"? We are talking about millimeters here and the steering wheel could be off-center...
Rolf that is a very good question... In one of my previous video's when I was rebuilding the front , there I have set the steering house/ steering wheel in the middle position by just measuring extreem right and extreem left movements and then set the steering house to the middle position. Then fit the steering wheel in a straight position and have it marked. At that time yiu don't care about the toe , because now that you have the steering house in the middle position we can adjust the toe
@@D3Sshooter Yes, I saw that video as well and it makes sense. However, if you have a standard car and want to make the toe adjustments. You can always roll the vehicle back and forth and hope it lines up nicely. But as said, it is just millimeters of in or out... Do you have a trick up your sleeves other than what has been mentioned?
Of course there are always more ways of doing the same thing the string method is accurate if all the wheels hubs are perfectly straight one other method which i was taught and claimed to be most accurate is to scribe a line on the tires and then measure between the front and rear of the tire at the line this eliminates any run out in the wheels then there are the toe plate that many teams use and may not be as accurate but if your using that method and measuring results as in steering feel and lap times it could be the fastest method and of course wheel fixtures could always be used such as youd see in a alignment shop then its only as precise as the equipment used like you i am a old guy with over 50 years of automotive experience working on vehicles and racing with one track lap record to a car I set up the suspension on that the driver/ car had many years racing at
Thanks for the comments Paul, good points...I never used that method.. I shall try it .... the best is of course wheel fixtures ( with small rollers ) . I verify the run-out if he rims before I start... maybe I should have stated that
Steve, Minis being FWD have a slight toe out to compensate for the drive shaft forces would this be the same on the rear of your race car where you have CV joints Just a thought ? Cheers Dave
Dave indeed FWD cars have the tendency when accelerating to push the wheels more to the center. Especially with standard bushes are used. That is why you see sometimes Toe Out on FWD's to compensate for that effect. In my case I have no bushes... In a RWD car the opposite takes place,
Steve, That‘s a good point and the other factor with a Classic mini is the steering rack is attached to the toe board on the body and the subframe is rubber mounted to the body not solid mounted, I have mounted my subframe on my track car with solid alloy spacers and the steering is direct. No good for the road but great on a track. Cheers Dave
The wife ribs me all the time about my string and bars. I use it on all our cars. The string never lies. I use a high visibility very thin fishing chord. My bars are set with electricians tape...never even thought of a tube cutter.
I'm a little unsure about how much you adjusted for toe. Did you adjust each front 1.5mm and each rear 1.0mm? That would give you a total of 3mm and 2mm toe front and rear...or at least that's how I learned to do toe. Is that right or did I miss something. ETA: Your actual toe is greater that what you've set since the toe is actually occurring at the tire surface, further out than the wheel rim. That's why some toe gages measure in degrees.
Rick, a typical setting is about 1 to 1.5 for this kind of mono seaters on the rim. Measured per wheel...... At the end I have set it to 1.5 mm front and 1mm back.... of course you are right that using mm instead of an angle is not that accurate ( as you stated , tire....) . Toe references are sometimes per wheel or total, depending the spec provider. I have a FF-1600 Hawke, with all the baseline geometry factory spec's ( lucky me) and they also specify toe per wheel in mm... ( 2 mm). I have seen other specs with total toe. So yes, you are right .... Of course one can calculate the 1.5 mm in degrees... that is 0.239°
@@D3Sshooter So what exactly did you do to each rear wheel, it's not clear in the video. And how did you make the determination on front toe since it did not show you taking any measurements on the front left wheel.
@@rickden8362 , as the video shows at each rear wheel the front part of the rim is 1 mm further away from the string then the rear part of the rim. The same method is used on the front wheels ( with the steering wheel in the middle position and locked ) . There the front of the rims are 1.5 mm further away from the string than the rear side of that rim. Same procedure is applied as in the back.. I have not put repeating footage of the same process in the video. Thanks for asking
@@D3Sshooter So, just so i have this right in my mind, ''total toe'' in the rear is 2mm(1mm on the right + 1mm on the left). And ''total toe'' in the front is 3mm(1.5 on the right + 1.5mm on the left). I just ask this since it wasn't shown on the video. When you reassembled the suspension, did you verify it was tracking straight with the center of the chassis?
@@D3Sshooter I've had 3 MGs. A 60 A, a 68 B and a 67 BGT. Living in the Midwest, it wasn't the smartest thing since the heaters were inadequate, and the electronics sucked. On the GT, I rebuilt the engine and put a higher lift, longer duration cam in it. Got a few more HP, but the increase in mileage was surprising.

Never thought of using a tube cutter Steve. I made my bar marks on a lathe, not running, just turned by hand.
Another thing I have learned today !
Thanks for the comments victor, and yes on the lathe that works also very well.

Thanks for the comments, and great to hear
I do my own string/ measuring tape alignments but can't decide if I like more or less toe out on the fronts 🙉
