well i agree that the stock flywheel lightend is good idea!! i have had mine done and it works fine!! but about the clutch net clutch? i had an rps which is made by clutchnet i think and it cost just under 400 and lasted 5000 miles in a stock b16a engine!! i was not happy at all!! ohh and trust me the stock lightend flywheel is a damn good idea because it is just the right weight! too light is not better!!
