Hope this provides some clarity, my original post covers everything regarding roll centre with the exception of its dynamic nature.

when you add shims to the upright you change how aggressive the camber gain is.

nitro junkie just a few questions.
when you say "lower front roll centre" do you mean taking shims out from under the top a arm on the inside baulks?
also rear lower roll centres means placing the inside camber link at the lower hole right? (also "A" block = low right?)
or is it the other way around?

Placing the camber link lowe on the inside is RAISING the roll centre...

ADJUSTING ROLL CENTER
The way that you adjust the roll center differs from one car to the next. However, the
theory is the same in that you want to change the angle of the suspension arms by
making them more tilted or more flat horizontally.
To fine-tune roll center, make changes to the angle of the upper arm.
To make larger changes to roll center, make changes to the angle of the lower arm.
It is very important that you have the same settings on the left and right sides of the car.
IMPORTANT!
Changing roll center settings impacts several other settings on the car, such as
downstops, camber, and ride height. When changing front or rear roll center, re-check
your other settings.
WHEELBASE
Wheelbase refers to the horizontal distance between the front and rear axles. Changes
to wheelbase can have a dramatic effect on the handling of your car, since it readjusts
the distribution of weight on the wheels, which adjusts traction. Not all R/C cars have
the option to adjust the wheelbase.
By adjusting the wheelbase at one end of the car, you affect the traction at that end of
the car. For example, by shortening the wheelbase at the rear of the car, you place more
weight over the rear wheels (resulting in more rear traction.)
EFFECTS OF WHEELBASE ADJUSTMENT
Longer
Car more difficult to turn around sharp corners.
Increased stability.
Better handling over bumps and ruts.
Better on more open tracks with high-speed corners.
Shorter
Car turns sharp corners more easily.
Increased steering response
Better on tighter, more technical tracks
the way you adjust the wheelbase is the c spacers that clip on the actual front upper hinge pin it self

has any one had problems with the 3racing 2speed all af a sudden first starts sliping its a real pain in the ass what i did to fix the problem is shim up the screw and washer as well as lock tight the spacer first gear sits on other wise it would slip on the 2speed shaft

This problem was an issue back about page 70 or 80. The 3 racing shaft, being titanium, just doesn't hold up. It wears down. Your best off using the K factory steel light weight hollow shaft.

"the way you adjust the wheelbase is the c spacers that clip on the actual front upper hinge pin it self "
Could you explain this to us. The " C spacer " (or caster clips) that you are reffering changes the caster, NOT THE WHEELBASE !! "
Now, on a xray FK05 or a T2, you can change the wheel base in the REAR ONLY !!!!

Track width, you can change ( 198,199,200mm ), not wheelbase. Trust me, i've spoken to Swauger about this afew times and I had to modify the rear for a shorter wheelbase for my MTX-4.
