Hi.
I noticed that sometimes the basic difference in setups are the shims under the ball studs under the camber links.
What effect does the following have in the handling of the car?
1. Front - increase no. of shims under the ball stud
2. Rear - increase no. of shims under the ball stud
3. Front - shorten the camber link length
4. Rear - shorten the camber link length
Thanks.

In addition to changing roll centre, changing the relative height of the ball studs (inner to outer, and also with respect to the arms) alters the change in camber from rest to compression. "Camber rise" is the common term here. A shorter upper link typically means more camber rise on compression. It does on our cars anyway.
Ideally, you want the camber when rolling to maintain the idea amount of contact patch for the type of corners you are dealing with. And that will change based on your driving style, the amount of grip available and the camber of the corner itself! The higher the contact patch (flatter tyre with respect to the track) the more grip *that* tyre can generate.
Still a vague answer, I know, sorry
Get the hudy set up book - it goes into heaps of detail. Also says when things should be changed.
The challenge is to get good enough to know something is occurring and when to change it!

Guys I need some help.
My steering will not return to center. When I set up the steering if I turn it right or left it will not return to center and is about 1.5 degrees off. It happened after a small bump to the boards.
I thought maybe it was the servo. So I tried a new and different one, no luck.
I thought then maybe it was the servo saver spring. So I screwed on a servo horn direct, no luck.
Everything looks straight, nothing bent. The steering has no binding when completely disconnected from the servo.
I am at a loss, anyone with some ideas?

Same problem. Tried everything possible to correct this and just end of living with it, besides this and my issue with killshot motor mounting spacing its a good car.

Problem is I can't drive well enough to deal with it. It veers on the straight because it doesn't return to center. That was my problem.
