If you’re building a serious 350Z and want strong holding power without going full harsh race clutch, this is the top-tier balanced performance option in Exedy’s range.

Exedy’s cushion button design bridges the gap between aggressive motorsport clutches and street usability, making it a popular choice for performance 350Z builds that still need some drivability.
