I have it in my AI/X car. I am extremely happy with it. I tested it in my AGS car as well and was much happier with it over my stock clutch. I have run Centerforce, King Cobra's, heavy duty FRPP, you name it. It is the only clutch that will take a lot of abuse and just keep on giving.
It is significantly lighter weighing in at 18 lb's for both clutch and flywheel, it is a sintered iron material which won't give up like an organic material, and yet will take more abuse like slipping the clutch unlike the majority of other small diameter clutches. It is a great in between clutch of a stock setup, and a small button muliti disk clutch in that it can be street driven without any problems, road raced and take the extreme heat and pounding of well over 500 hp at the crank as tested and proven by my AI/X car. It will also rev faster since the reduced weight and lower polar movement of inertia which helps in acceleration, and in deceleration, downshifting, and braking. Something else to consider is it is also rebuildable which in the long run may save you money unlike a stock setup where you replace the whole unit, you can replace just the disk when the time comes. I have a lot of miles on them, and haven't replaced a part yet. If I can answer any more specific questions, please let me know.
