Ok, so for reasons unknown to me, my clutch is pulsing when slipping/feathering to the point where it just vibrates the whole car. This only happens once the clutch is well up to temperature and the best way I can describe it is a feeling similar to when you get a break rotor pulsing. When the car is cold the clutch is nice and smooth but as soon as it warms up and especially when slipping up a hill it just pulses/vibrates like a *****. The only thing I can think of that could possibly be a cause is a hot spot on the flywheel or some material built up. I have an ACT prolite flywheel and Clutchmasters FX300 clutch. Both have about 30K miles on them, but wtf. If it is a material built up, what are my options ? Will I have to resurface or get a new flywheel? Can I just beat on the Fker, do a bunch of launches? Anything, suggestions from anyone who has had some similar expereince please

 

video camera on record then rev limiter dump in second gear.

it will reserface the flywheel without having to take it out of the car
