Pro-Adjust service kit for the Cusco RS plate-type rear LSD in the BNR34 Skyline GT-R — shims and springs to retune preload and ramp bias on the existing unit. Useful after track use when you want to tighten or loosen engagement without pulling and replacing the whole diff.

Cusco's Pro-Adjust system is what separates a serviceable racing differential from a disposable one.
