Sorry to hear you went with spec,i just went threw a stage 3 in 40 days before winter,lets start off by saying it was shimmed correct and installed by a very reputable speed shop in my area that is well aware of specs issues,i never once raced the car, did the break in perfect,ok so one day i was driving and the clutch completely crapped out,i thought for sure that it was a master/slave issue,i mean it couldnt be the clutch and flywheel its all new right,so i take my car in and i get a call a few days later,they said umm you need a new clutch, they were just as shocked as i was,i mean my flywheel had major hot spots,disc material was pretty much gone,and a few rivits at that,it looked like it came out of a 300,000 mile race car,now remind you this doesnt even have 900miles on it yet(i drive alot for work) then i tried getting it under warranty, well thats almost impossible,1. I was told it was installed wwrong ( we proved that to not be why) 2.i was told the break in period wasnt done right ( i said your right im going to drop that kind of cash and not do that correct) 3. This was what i was told was the final say so before they tell you to screw off , i was told debris caused this and they couldnt do much for me,i said ok we shoveled a huge amount of dirt in the trans before putting it back in,then i was told i could send it in, i was pissed like you wouldnt believe at this point,and like i said from researching thats the screw you line,got a monster, and havent had one issue what soever,that pos stage 3 cost me alot of money,i dont do trans work nor do i have a race car,its only a cammed with bolt ons,i hope you just have a cylinder problem,just beware of that company,never again will i buy there crap or ever tell someone to buy there crap,they acted like there product couldnt have failed,but yet there was more fails than just mine,again i feel screwed by them,just making you aware of if it is a clutch what your in for again i hope thats not your issue but sounds like how mine started,
