how thick??

[1st1down]

Ok Experts I am help building Two cars one for each granddaughter this year we are going a little thinner, we have good luck with the basic wedge design so my question to you is...How thick should the maximum be...RIGHT NOW I am at 1/2 thick for maximum in the rear.

What say ye gents?

I like it. 1/2 an inch sounds good to me. You want to be able to get roughly 1.25 - 1.5 oz of weight behind the rear axles if you can, so dont go too thin in the rear.
