If you're looking to amp up your ride's performance, the Advanced Clutch HD/Race Rigid 6 Pad Kit NX4-HDR6 is where it's at. This kit features ACT's Heavy Duty pressure plate, which is a fan favorite for good reason. The unique diaphragm design not only ramps up the clamp load but also keeps deflection in check, so you get a clutch that lasts longer and performs better. Every diaphragm goes through a four-stage heat-treating process, ensuring it can handle whatever you throw at it.
Now, let’s talk about the 6-pad rigid race discs. These aren’t your average discs; they’re crafted from high-quality ceramic friction materials that can take the heat. The chrome-moly hub is heat-treated, giving it the strength and durability you need for serious driving. The lightweight and rigid design means you’ll experience quicker shifts, which is a game-changer on the track. Just a heads-up, though: the engagement is a bit harsher, but that’s the trade-off for faster shifting. Plus, if you're pushing larger clutch sizes, this setup can absorb more heat, making it a solid choice for those hard runs.
