Spend less time wrenching and more time on track, with our new camber link shim set for the ARC R12. Made from 100% carbon fiber, their clever design allows racers to adjust the inner camber link position on the ARC R12 with ease. No longer do you have to completely remove the upper link brace, add or remove spacers, then try to reassemble everything without dropping any spacers! With our shims you simply loosen the screws, remove or add shims as needed, then retighten the screws. The set comes complete with 4 shims in 1.0mm thickness and 4 shims in 1.5mm thickness.
