ACT HD/Race Rigid 4 Pad Kit Acura Integra | Honda CR-V | Civic | del Sol 1994-2001 - AI4-HDR4

Alright, gearheads, let’s talk about the ACT HD/Race Rigid 4 Pad Kit (AI4-HDR4). If you’re serious about performance and want a clutch that won’t back down, this is your ticket. It comes with ACT’s Heavy Duty pressure plate, which is a favorite among folks who push their rides to the limit. This isn’t just any pressure plate; it’s designed with a special diaphragm that amps up the clamp load while keeping deflection to a minimum. Trust me, that means your clutch is going to last longer and handle more power.

One of the cool things about this kit is the four-stage heat-treating process that all diaphragms go through. It’s like giving your clutch a little extra armor. Plus, the precision cover stampings ensure that you get the rigidity and consistency you need when you’re racing or just enjoying a spirited drive.

The 4-pad rigid race discs are where the magic really happens. Made from high-quality ceramic friction materials, these discs are tough and ready to take on the heat. The chrome-moly hub is heat-treated as well, so you know it’s built to last. The lightweight design means quicker shifts, which is a game-changer whether you’re on the track or just having fun on backroads. Sure, the engagement is a bit harsher, but that translates to faster shifts, and who doesn’t want that?

Now, if you’re considering this clutch, just a heads-up: it’s best suited for smaller disc sizes and engines. So, if you’re running something like an Acura Integra or a Honda Civic from the late '90s, you’re in good shape. It’s designed for race use, so keep that in mind if you’re thinking about daily driving with it.
