If you're looking to upgrade your clutch setup, the ACT CA1-HDSS kit is a solid choice. This kit combines their Heavy Duty pressure plate with a performance street disc, both of which are tried and tested by folks who know their cars. The pressure plate features an exclusive diaphragm design that cranks up the clamp load while minimizing deflection, which really helps extend the life of your clutch. Plus, every diaphragm goes through a four-stage heat treatment, so you know it’s built to last.
The Performance Street disc is where it gets interesting. Made from high-quality organic materials with a good amount of copper, it’s designed to handle heat like a champ. The steel-backed lining adds durability, so you won’t have to worry about it giving out on you at the worst possible moment. And the reduced marcel means quicker shifts—perfect for those who like to keep it sporty.
