    • Q: Upgrade  sphillips.islreal734025 years ago

      I bought a ACT heavy duty street performance clutch kit. After 3000 miles the clutch is slipping. May it's because I didn't realize till I dynoed the car that it's putting down 450WTQ. Should I upgrade the disc to this 6 puck or with that power replace it with an Exedy twin or Tripple plate clutch? I do not track the car but do love to launch hard on the street from time to time...

        A:  This disc will work well for you and you can use this rather than replacing the full clutch kit.
