2018 with 20,000 miles

I was at a track day July 2, 2020 during which the ambient air temp was in the low 90s. In the last two sessions after 7-8 laps it felt like the clutch slipped in 3rd and 4th gear (wasn't using 2nd at this track). Coolant never got over 220 (so the engine wasn't super hot which could make the clutch hotter). I don't slip the clutch at all - in fact, I may be the opposite if I am on any end of the spectrum of slip vs. side-step.

Video (I had a hard time noticing the slipping from watching the video, but it's what ended my last two sessions, so I either went off right away or tried to do a slight cool down lap):

Power mods: VF/HEX Stage 2, CSF FMIC, High-flow Fabspeed cat

A couple questions:
1) Has anyone else experienced this?
2) What sorts of HP numbers have people seen with stock clutch? Granted, mine was on a hot, tracking car vs. sitting warm on a dyno.
3) I am feeling like I should have eliminated the CDV when I first got the car.

I would appreciate anyone's thoughts regarding this topic. Also, I have a couple month left on my warranty, so I'd like to figure out what to do. Part of me wants the dealer to take partial blame because the CDV causes slip that would wear the clutch prematurely, so their design is partly to blame. Thoughts on that piece, too, would be appreciated.

Considering The transmission in our cars is the same one used on the F8X platform and they regularly see high power levels between 500-700wtq. It can definitely handle high power

Our clutches are very very strong.

Maybe OP's clutch is defective?
