i burned up a Centerforce clutch in my truck and will never put one back in. the extra holding power actually made the problem worse when the clutch went out b.c. it held metal to metal on the disc and pressure plate....and because it still drove it took me a while to figure out what the hell the problem was. when i finally got the clutch out i ended up having to replace the flywheel too....not cheap. since then i've burned up 2 LUK clutches. one wasnt really "burned up" per say...but it had a stick stuck in the pressure plate and bent the forks. the other i just replaced b.c. it was lifetime warranty and i was putting a 300lb transmission in that i really didnt want to take out if the clutch went out in a month.
