Considering there is so much contraversy over F1 products ive decided to purchase a stage 2 clutch and their 11.5lb chromoly flywheel and write a review on it. So first ill start with customr service. i ordered my clutch and flywheel from Gripforce.com for 250, and paid for the 2 day shipping. it arrived the second at around noon. Everything was packaged well including the clutch, pressure plate, throwout bearing, install tool and flywheel. No visual defects or damage. The clutch disk has good contruction. nothing loose. rivets nice and tight. torsion springs are stiff and secure. the flywheel is perfect cut and has a tight press fit pilot bearing. Ive installed the clutch and flywheel and now have 100 miles on it. Pedal effort is small with the stage 2. the clutch grips very well. either semi short or really short if you drop the clutch. slight clutch chatter was noticed during the first 50 miles, as a lot of clutches do during breakin. No more clutch chatter is present. Throttle response with the flywheel is amazing. definetly noticed over the 22lb stock flywheel. Overall this product is GREAT for the money. i would recommend it.
