If you're looking to amp up your ride's performance, the ACT Heavy Duty/Performance Street Rigid Kit (BM16-HDSD) is a solid choice. This kit features ACT?s go-to Heavy Duty pressure plate, which is designed with a unique diaphragm that boosts clamp load and minimizes deflection. What does that mean for you? More grip and better clutch life, plain and simple. Plus, every diaphragm goes through a rigorous four-stage heat treatment, so you know it?s built to withstand the heat of the moment.
The pressure plate is crafted with precision cover stampings, ensuring it?s both rigid and consistent. And let?s talk about the clutch discs?these aren?t just any discs. They?re made from premium organic materials that have a high copper content, which means they handle heat like a champ. The steel-backed lining adds to their durability and burst strength. You?ll appreciate the chrome-moly hub, which is heat-treated for extra toughness. The rivet design is carefully selected to maximize strength, so you can trust these discs won't let you down.
One of the standout features of this kit is its lightweight design. It?s the lightest street disc available, which translates to quicker shifts. You get race-proven performance with the kind of street manageability that makes it perfect for daily driving or weekend track days.
