Great clutch I am using it with a Nismo flywheel and holding 550 on a Mustang Dyno, I know someone else with similar power that has beat the hell out of it on the drag strip with slicks and even broke axles and clutch still going strong.

 

i am also thinking about going with the cm stg 4 clutch. i like what i am hearing here about the 6puck design.

 

Pretty good clutch, I had it installed last week as well as the clutchmasters lightened flywheel, I just find it hard to drive in stop and go traffic, the light flywheel makes it difficult.. chatters a bit at low RPM which is somewhat embarassing LOL...

 

I actually had a slipping issue with a stage 4. Called CM and were the absolute best company to deal with. They sent me a new prototype stage 5 single disc with pressure plate no charge. I can also say that I have no chatter like alot of aftermarket flywheels get.

 

BUMP FOR ClutchMasters!!!!!
