If you're serious about performance, the Advanced Clutch HD/Race Rigid 6 Pad Kit CA1-HDR6 is worth a look. This kit packs a punch with ACT's go-to Heavy Duty pressure plate, which is designed with a unique diaphragm setup. This means it not only boosts clamp load but also reduces deflection—so you get a clutch that lasts longer and performs better under pressure. Each diaphragm goes through a four-stage heat-treating process, which really amps up its durability and performance. Plus, the precision cover stampings ensure everything stays rigid and consistent, even when you’re pushing your limits.Now, let’s talk about the 6-pad rigid race discs. These bad boys are crafted from high-quality ceramic materials, which gives them a serious edge when it comes to heat tolerance. The chrome-moly hub is heat-treated as well, so you know it’s built tough. The lightweight, rigid design means you can shift faster, which is a game-changer on the track. Just a heads up, the engagement can be a bit harsher, but that’s the trade-off for quicker shifts. If you’re running a larger clutch size, this setup is perfect for absorbing more heat, keeping everything cool under pressure.For those who like to get their hands dirty, installation is straightforward.
