I believe its 10.5 lbs. But I do not recomend blitz, unless you going to put a turbo or a supercharger on. That is a serious clutch my buddy put one on his celi and it chatters alot. For a daly driver go with ACT or TRD.
Yes I believe so too ... and that clutch will be very hard to drive with on a celica. The single disc design will make it so the clutch is either on or off ... there will be pretty much no slippage. You would get excellent response from the clutch but it will be very hard to start off, you'll have to rev the engine a lot to keep it from stalling when you start off.
I would go with a 4 or 6-disc clutch ... the more discs the better and easier daily driving will be but also with more discs you lose that performance because more slippage is allowed to smooth out daily driving.
