So I have been trying to search all over the place for more info on this clutch. I like it because it is not organic or kevlar, is from a reputable company, and I THINK should be more than sufficient for my power goals and use, and price is very reasonable. From what I could find it appears that honda guys are able to hold around the ~290whp, although their discs are 220mm in dia. vs 200mm for 1.6l and 215mm for 1.8l. I was hoping to switch to a 1.6l clutch and flywheel to shave an extra pound or two. My thought was that while the stage 2 1.8l version may have more clamping force; the 1.6 should still have ample clamping force for my power level and use.
SETUP: I am should be around 220whp 200tq, and primarily Autocrossing, with maybe a couple of drag races. I will be running 225 RS3's primarily and a Torsen 4.3 (not like that particularly matters). However, it will also be my DD.
I can get a better deal on Exedy than ACT So I dont want to hear how you have an ACT HD
and quite frankly ACT![Jerkit](https://www.miataturbo.net/images/smilies/jerkit.gif)
Now, have any of you guys personally driven an exedy stage 2 ( and I dont mean in some other car)? Im curious to hear opinions, and how the engagment feels since it is essentially a 3 puck. I think it may be overkill for my hp, but maybe not so for its use??

Well I finally found some actually figures for the stage 1 and stge 2 clutchs from exedy. I figured I would post it for future reference.
The Exedy Stage 1 (organic):
1.6l: 125ft/lbs (200mm disk)
1.8l: 168ft/lb (215mm disk)
Exedy Stage 2 (cerametallic):
1.6l: 142ft/lbs (200mm disk)
1.8l: 191ft/lbs (215mm disk)
Which would lead me to believe that it perhaps wont be sufficient, granted I wont be at its holding limit all the time. The stage 1 as is, is insufficient for the power I'm making now let alone in the future.

@ Braineack, was that a 1.8 clutch?
I did want to stray away from organic originally because I thought I remember hearing that at the limit, when they begin to slip the organic material will glaze over and then not hold for ****, and pretty much toast!
Is there any truth to that?
