I have decided to replace my clutch/pressure plate with a ClutchMaster FX-300 or FX-400. They are roughly the same price...about $500. Seeing as how even the ultra-expensive clutches seem to have longevity and engagement issues, I've decided that I would rather buy 4 or these clutches rather than 1 of the super-expensive types (installation costs excluded).

That said, for those that have used these clutches, should I get the 4 puck FX-400 which has ceramic discs and a slightyly harsher engagement, or the FX-300 which claims to have super smooth engagement. Both clutches have pedal pressure that is slightly greater than stock.

FX-300 claims to have 110% more holding power

Let me know your thoughts on these items. I plan on needing a clutch to support from 450-550lbs of torque. A couple people I know have beat the living crap out of these clutches without any issues or slippage.

My stock clutch is officially toasted. I could barely get the car on the transport to Charlotte...

I installed both these in cars at the shop. After driving both I've always used the FX-300 in my cars. Never had slipping problems and very smooth enagement. The FX-400 does take a little skill to move out smooth. But it's completely streetable just not as smooth as the FX-300. I doubt you would be able wear the FX-300 out unless you don't follow the break-in.

Thanks for the feedback. So it sounds like the FX-400 has a bit of chatter to it when launching from a dead stop? How bad is it?

If my goal is in the 500lb/ft torq range, would you still suggest the FX-300 or the FX-400?

I have a cluthmaster stage III in the SS and love it. When the time comes for a clutch change for the G35, a stage III clutchmaster is what I'm getting.

The FX-400 will chatter a little in slow stop and go situations. Yes I still recommend the FX-300 for your goals. It can take the power. It will only fail if you abuse it but, any clucth will fail under those condtions.

fx-300 it is then!

Trust me you will enjoy it the pick up and engagement is much better than the stock clutch. Almost any thing is. Just be sure to break it in right (little/no slipping for 500 miles). As soon as the stock one goes for me I'll get one and a light weight flywheel (one of the 14lb ones).

Hey gq. I am ready for clutch as well, and the shop I was at yesterday, really spoke highly of the clutchmaster.

So I am also looking at them, or JWT combo


Gary, would that be the Clutchmaster Aluminum FlyWheel ?

I'm looking at the JUN chromemoly flywheel just because it's a one piece unit.

Almost all of the lightweights are around 14lbs ie.JUN, JWT, UR, Clutchmasters and Stillen. I just would prefer a one piece unit and JUN is the only one right now.
