Yup. I'll be running the carbon/carbon single with steel flywheel. RJ said the aluminum would be "dog box loud."
I asked him if we could get a steel flywheel that shaved a few pounds, and he said...maybe lol
Just shipped one to an EvoM member since his car will be done before mine.

Yup. I wish the aftermarket made a stock weight flywheel. 15lbs is really light enough as it is. Going to the ACT streetlite flywheel (12lbs) made getting the car going noticeably more sensitive to clutch and throttle pedal inputs.
The owner of SpeedSport (RJ) says there should be no high-speed lock out issues. A local racer won the Modified AWD class in RTA. That's all high-speed, high RPM shifting. And he has the steel flywheel clutch on his car

Twin disc carbon-carbon pull type isn't too much more, if you really want a twin In fact, it's only $200 or so more than the Exedy twin cera-metallic.
My car isn't on the road yet. I sold one to Biffman, and last time I checked, he was still getting his assembly balanced.

Anyone running this clutch yet? I hate my comp stage 2 and want something that will hold good power but not have any stiffer of a pedal. And not smell if you barley slip it too much.
Why do you hate the Comp? I'm past 15k miles + light flywheel daily driving in a hilly part of the country, with over 500lbs of torque. Holds like a dream, never slips, and shifts better than my ACT could have hoped for.

Mainly if you barely slip it too much it will stink. Over 7000 it doesn't like to shift fast. Pedal feel is good but seems if you slip it to much on a launch it glazes the flywheel and will slip.
THe SPeedSport is in the ballpark performance wise of an Exedy Twin, but without the rattle of a twin disc.
The single carbon/carbon has a 10% heavier clutch pedal feel as rated from SpeedSPort. Also, the carbon will take a lot more abuse than the comp 2, but the clutches are not comparable price wise. THe SPeed Sport is about $700 more from what I can tell. Then again, you're getting a pretty high performance clutch.
