The Corvette is a remarkable drift chassis, however, it may have certain limitations in comparison to other platforms due to the positioning of its front upper control arms within the front wheel. The FDF Arms are specifically designed to address this issue by utilizing high-strength alloy steel and a modified mounting point, resulting in the maximum clearance on both OEM and aftermarket drift knuckles. In contrast to the OEM upper control arm, the FDF arm offers an additional 10 degrees of clearance, significantly enhancing the vehicle's angle potential. Moreover, the replacement of factory rubber bushings with chromoly rod ends further enhances the handling characteristics of the vehicle.
The upper control arms are length adjustable using the rod end adjustment range. The range is limited due to the mounting angle, so to further increase the control arms lengths, you can add upper control arm shims.
