Description: The MR1-HDR4 kit by ACT features their popular Heavy Duty pressure plate paired with a 4-pad rigid race disc, engineered for high-performance racing applications. Employing ACT's exclusive diaphragm design, the Heavy Duty pressure plate enhances clamp load, minimizes deflection, and maximizes clutch longevity. Each diaphragm undergoes a four-stage heat-treating process for outstanding performance. Precision cover stampings ensure the rigidity and consistency of ACT pressure plates. Crafted with high-quality ceramic friction materials, the 4-pad rigid race discs feature a chrome-moly hub heat-treated for durability. This lightweight, rigid design facilitates quicker shifts and ensures reliable performance. While engagement may be harsher, the 4-pad rigid race disc enables faster shifting, making it ideal for smaller disc sizes in compact engines.

Features:

  • Feel: Light to moderate pedal effort, aggressive engagement, increased gear rattle
  • Life: Moderate friction life, extended by ACT's exclusive diaphragm design; rigid design may increase spline wear
  • Quality: Carefully engineered, precisely assembled, accurately balanced, uses select ceramic friction materials for high heat tolerance and maximum performance
  • Recommended Use: Recommended for race use only
  • ACT Difference: 100% clamp load tested and dynamically computer balanced for smooth high RPM reliability

Good and Cheap
Works great on my 1997 Honda Accord EX 2.2L. Great value for the money. Installed it myself. Only a 30 day warranty though.

Body of starter is longer than the original. Still fits but changing the starter on a BMW space is at a premium. Also had to grind down edge of battery cable to fit on solenoid. Aside from that starter was fine. Working well
