Im going to replace my clutch as soon as i wear my other one down, and im wondering what a good racing clutch is? some examples...centerforce clutch kit and extreme clutch kit. Just some i saw i have no idea whether they're good or not.

I have been very happy with my Clutch Masters Stage 4.

Takes awhile to break in to where it isn't really grabby, after that not bad at all.

I had the stage 4 (4 puck, sprung hub) on my FrankenTiva (Festiva w. Miata Motor and ECU) and man..that thing GRABBED with a vengance. Chirped 3rd with ease. Course, the FT only weighs what...1400# GVWR? I had to rev it up higher and almost slip the clutch everytime in traffic. I want just a notch under that...so, 3 it is...I just want to see what ditching the DMFW does infavor of a light FW...I cant wait..hope its nice and rev happy!!

So I went to the SPec site and saw that they label their clutch kits by TQ capacity. For example: Stage 1= TQ 299, Stage 2= TQ 340, etc.

I might be adding an SC in the near future. But I doubt I'll be exceeding 300 HP. Would the Stage 2 be a good option. I mean I also want a clutch that is not too stiff to operate since I have to be driving around town daily.

from some research I did, Clutchmasters holds more power with less clamp force than SPEC...........just based on that it shows how much more advanced CM is. If my decision were between those two I would go with Clutchmasters hands down.

Keep in mind I don't have experience with either of these clutches on my car so this is soley based on the information above.

Here is an example. Spec Stage 4 rated to hold 339 ft-lbs of torque (all clutch companies measure this rating at the flywheel, just FYI)............and it takes 2000lbs of clamp force to accomplish that.

Now the CM4 on Tom's car has held 440hp at the wheels, which is over 500hp at the flywheel, for a long time and many, many trips to the track on slicks. They accomplish this with only 1500lbs of clamp force.

And to put it into perspective, stock clamp load is roughly 1050lbs.

True but its an organic disc so the longer its pushed hard the more it will fade and not hold up. I was trying to compare apples to apples, both stage 4's from CM and SPEC respectively have ceramic disc which will hold up better to extreme heat caused from drag racing with slicks or long track times on a road course. Comparing a ceramic friction material vs. an organic material is not a fair comparison.
