Introducing new carbon fiber roll centre shim sets for the ARC R12. Available in 1.0mm and 1.5mm versions, the shims are used to raise the R12 suspension arm mounts, allowing roll centres to be raised in larger increments without stacking multiple shims.
Raising the roll centre releases the car from excessive grip through a corner, allowing for improved flow and corner speed. Features a unique design that allows the same shim to be used under all 1-piece toe blocks. This is the 1.0mm version.
