If you're serious about performance, you’ll want to check out the ACT HD/Race Rigid 6 Pad Kit, specifically the NZ1-HDR6 version. This isn't just another clutch kit; it's designed for those who really push their machines to the limit. The Heavy Duty pressure plate here is a standout, utilizing an exclusive diaphragm design that ramps up the clamp load while keeping deflection at bay. That means you get a clutch that can handle the heat and last longer, which is something every gearhead appreciates.
Now, let’s talk about the nitty-gritty. Each diaphragm goes through a four-stage heat-treating process, so you know it’s built to perform under pressure. The precision cover stampings add a level of rigidity and consistency that you just can’t overlook. And then there are the 6-pad rigid race discs—crafted from high-quality ceramic friction materials. These discs are tough, with a chrome-moly hub that’s heat-treated for extra strength. The lightweight, rigid design means you can shift quicker and enjoy a smoother experience overall.
But fair warning: the engagement on this setup is a bit harsher, which is part of the trade-off for that lightning-fast shifting. If you’re running a larger clutch size, this is where the magic happens; it absorbs heat like a champ, making it perfect for those intense track days.
