ARC R8.3 & R8.3E adjustable front & rear shock base
From ARC, the adjustable front and rear shock base are the latest option parts designed for the R8.3 and R8.3E. This allows the shock angle to be adjusted by adding or removing shims. Compared to traditional shock towers, racers can adjust the shock angle in much finer increments to better fine tune the handling of their car, the more shims below the shock absorber the harder the suspension. Both shock bases also feature a 3mm carbon brace that bridges the left and right sides of the shock base. This brace can be added or removed to adjust the flex of the front bulkhead. With the plate installed in the front there is an increase in initial corner speed, while when the rear version is installed there is an increase in rear end stability.
