would have thought it would be ok, i have a g60 flywheel from the dealership and it doesnt make noise or feel different. only thing is it does vibrate a little with the clutch disengaged, you can here it when you rev when the car is stationary. doesnt feel any different.
i guess yours will be the same, except the symptoms i mentioned above will be more noticable?
go for it i reckon, will make a big difference on the road!
