Recommended Usage Scenarios

  • Recommended for Street and Race
  • Quicker engagement
  • Quiet operation
  • Best organic friction material, improved hub and burst strength

Vehicle Applications

  • Mitsubishi Lancer Evolution VIII 2003-2005
  • Mitsubishi Lancer Evolution IX 2006
  • Mitsubishi Lancer Evolution X 2008-2009 (GSR / 5-speed)

Key Features

  • ACT carefully selects the right amount of cushioning between the linings to allow for good engagement characteristics without sacrificing performance
  • Most ACT spring centered assemblies use bushings and cone springs similar to factory clutch discs. This creates frictional dampening which improves clutch life and reduces noise
  • Spring retainers by ACT utilize a wrap around spring window that not only gives liberal support for the springs, but also reduces stress concentrations that are a common cause for failure. (Offered on most ACT Modified and Performance Street Discs)
  • ACT performance linings are steel backed for maximum burst and rotational strength
  • We carefully broach our splines to ensure exact fit onto transmission input shaft for long spline life and better clutch release
  • Heavy duty torsional dampening springs are stronger in most cases than standard springs and are provided in the best sizes and spring rates to suit the application
  • ACT Performance Street Discs feature a high copper content friction material. Through the use of copper the heat is pulled away from the surface. ACT achieves better heat tolerance and faster recovery from overheating
  • Top grade rivets are used to securely fasten the part together. Rivet design and rivet materials are carefully selected for maximum strength
  • Spring windows on most ACT street discs are heat treated to resist wear, increase strength and reduce the chance of springs popping out
  • ACT provides thicker retainer stampings for increased strength and reliability. (Offered on most ACT Modified and Performance Street Discs)
  • All modified, performance and many standard replacement discs are certified as meeting SFI Specification 1.1 and are legal in all racing organizations that require SFI certification
  • Precision stampings for disc components are manufactured using dedicated tooling. This allows ACT to offer the highest in quality and consistency
