Description

With these high quality Cyberdrive Racing SAE 4140 steel chromoly differential collars, we are strengthening really the only weak point in the 86/BRZ’s differential, if the stock one goes, the diff follows. They come with extended shims that need to be shaved for fitment, this is for 2 reasons, 1. the tolerances on each individual 86/BRZ will slightly vary, 2. to save money and eliminate surprise when finding a custom shim needs to be made.

These are highly recommend as a safety net to anyone who clutch drops, drifters and hillclimbers. For anyone who puts extreme load on the differential.
