Question , is there a limit to lower the rollcenter by shimming out the upperarm ?
I am new to tc racing , and is it right to think how lower the rollcenter , the higher the grip of the car ?
You can shim as much as you want, as long as nothing binds or rubs.
Lower roll centers don't always increase grip...... in fact depending on conditions you can actually decrease traction with it. What surface and tires will you be using?
