I've heard bad things about ACT or Centerforce, I don't remember which one. I'm looking for a clutch not too much stiffer than stock that can handle up to 500 horses. Also, what's the best tranny fluid? It's time for me to change it.

 

clutchmaster s4 6 puck.

for tranny fluid you can stick wtih the mopar atf+4 or try redline, royal purple, or amsoil. any will work just fine.

 

Redline FTW!

 

Is the clutchmaster what you are running? How's the action, is it daily driven material?

 

i've got the cm s4 6 puck w/aluminum flywheel. it's a great clutch, very streetable. chatters like a helicopter but that's what a race clutch will do
