ive driven a G with a stage1 clutch kit and its similar to stock with a slightly grabbier engagement. my question is how much of a difference is between the stage3 and stage4 discs? as far as how hard the pedal feels and the quickness of engagement? btw, i picked up a comp stage 4 clutch/flywheel disc but gonna get a new disc just for my piece of mind. NA power for now...should be atleast 300whp with the new motor, maybe a vortech down the road for 400-450 whp. ??
