ACT HD-M/Race Rigid 4 Pad Kit Mazda RX-7 1993-2002 - ZX6-HDR4

ACT HD-M/Race Rigid 4 Pad Kit ZX6-HDR4 Overview

If you're looking to elevate your Mazda RX-7's performance from 1993 to 2002, the ACT HD-M/Race Rigid 4 Pad Kit ZX6-HDR4 is a clutch upgrade that delivers. Designed specifically for the spirited driver, this kit features ACT's renowned Heavy Duty pressure plate, which utilizes a unique diaphragm design to boost clamp load and minimize deflection. This means you get a clutch that not only lasts longer but also performs better under pressure.

Performance Features

  • Light to moderate pedal effort ensures a comfortable driving experience while still delivering aggressive engagement.
  • Increased gear rattle gives you confidence during hard shifts, making it ideal for track days or spirited drives.
  • Engineered with high-quality ceramic friction materials, the 4-pad rigid race discs are built to withstand high heat and provide maximum performance.
  • ACT's patented Monoloc system replaces the standard two-piece wedge collar, ensuring uniform loading on the bearing and pressure plate for optimal alignment.

Installation and Compatibility

This kit is a direct replacement for your stock clutch, making installation straightforward for those who enjoy working on their own vehicles. The Monoloc's hardened chrome-moly steel construction promises durability, so you can focus on the road ahead rather than your clutch's reliability.
