Whats effects are to be gained by putting in or takeing out shims to affect roll center....
Eg i have a c4.1 just bought the exotec alu rear hub with the option to ajust r/c with shims
Run on both slippy and high grip tracks.
Its all new to me i have no manuals only raced since newyear...
Thanks for any none sarky informative replys in advance
