How to quickly set Caster and Camber on "Old Skool" front end.

First buy a AE or PArma Shim kit and start with the 2-degree caster shims for a Rev.3

This may be a bit difficult to explain, but:

Step 1

I take my rear axle off my car and set the car on my set-up board. I measure caster by lining up my camber guage on the kingpin and take my measurements. Its an eyeball measurement!! Shim on the front or back of blocks to adjust catser. I like between 2 and 3 degrees.

Step 2

I then measure from the set-up board to my stub axle and make sure both sides are Exactly the same height from the set-up board. If not-I shim it up.

I use any thickness paper product it takes!!! In my car right now are header card, business card and two thickness' of plain paper!!!


Step 3

Last-I put the rear axle back in, battery and all the wheels back on (Use a fresh set of trued tires!!) and measure the camber with the camber guage. Shim it up or down, but realize you may now have changed your caster and stub axle heights a little so go back to step one and check.

At a race where thers no time to do all of this-I WILL change my camber settings and not remeasure the caster-but I will check stub axle height. I am just VERY careful to add shims in such a way as to not have a big affect on caster.

The biggest thing is to think a step ahead the whole time!! IN other words-lets say you need to add camber on one side , but the stub axles too high comared to the other side already......hhhmmmmm-WHat to do? Yu gotta work out your options with the shims!!!

Like I said-A 12th scale is a scalpel. Its not like a sedan which, as Cypress said can be driven and forced around if need be.

Hope this makes sense!!
