OS Giken Super Single here.
Ceramic Metallic Full face.
And has dampened center.
No problem driving it on the street after 1000 mile break in.
Little over a year of autoX on it. Unlike other Auto-x we run events with a lot of open space (old airport)
So there is a lot of shifting. At least for me Supercharged and 4.4 gears.
I would call our Auto-xes at the old airport mini road courses.

I am making 377whp 250 wtq. I currently have a clutch masters stage 3. This POS only lasted a 1.5 days on a road course before it ran too hot and glazed over. Now its slipping like crazy. Please only provide input if you have an FI s2000 and track it. Sure the clutch maters clutch was great on the street, but it died after only a weekend on the track. I don't want to be recommended another clutch like this. I can't afford to spend $1-2K for things that "may" work. Looking for a sure thing to last years to come. Ok enough venting.
I am looking for a clutch that will
1.) Hold my power
2.) Can handle the heat from road course racing
3.) No Organic clutches. I hear this can't handle the heat on track with FI.
4.) Daily drivable

I am actually surprised to hear you had this problem because, back in the day, lots of us did the Clutchmaster's Stage 3 upgrade and have had some success.
Regardless, I believe the Competition Clutch setups are pretty economical and have been fairly durable and reliable for our cars. I would personally go that route.
Sorry to hear about your Clutchmasters setup.

Cerametallic
All of our clutches do have a pretty good sweet spot that you can ride the clutch before the friction of the metallic takes over and starts to grip up. Our set up is not "on/off" by any means. If you were in the
I would recommend the Super Single for the 400whp range which is dampened.
The Super Single has a torque capacity at the F/W of about 600ft.lbs., please keep in mind that this is static torque capacity, not dynamic!!!
It will easily hold 400whp,
as our lesser STR1CD single plates (for MINI and LOTUS) begin to show slippage on the dyno at 375whp.
The STR1CD singles have much less clamping force than the Super Single, in addition the S2k Super Single has a disk size of 225mm compared to the 215mm of the STR1CD.
The additional clamping force of the Super Single would create a heavier pedal than that of the TS2A or TS2B clutches. Our TS covers typically result in a pedal pressure close to stock, the Super Single would be slightly heavier. Both either the Stamped steel covers or the Aluminum cover kits would be adequate. The stamped steel units have a little less clamping force than the aluminum units, but also provide a slightly less heavier clutch pedal.
