Ultimate throttle response and faster acceleration at your command! UUC's exclusive-design "sprung hub" clutch design Stage II lightweight flywheel has been named one of European Car magazine's "Top 10 Products". This aluminum flywheel boasts the best features in its class (high-speed balanced, correct dowel hole, replaceable friction surface, Made In USA quality), but is designed to use the superior pressure plate design of the E36 M3, built with the correct 22-spline disk and release bearing for the 6-speed transmission. The total weight of this package is approximately 20lbs lighter than the original components, resulting in noticeably greater performance. This Performance Organic clutch option provides smooth engagement without any increase in clutch pedal effort. The advantage of a sprung-hub clutch design is improved resistance (and in many cases, complete elimination) of the residual chattering noise at idle that some lightweight flywheel-equipped cars can experience. UUC customers have been using the Stage 2 package in turbo or supercharged E46s with fantastic results. Our own testing has shown this clutch to reliably handle in excess of 400hp (Performance Organic) / 475hp (Segmented Kevlar). Kit comes complete with flywheel, clutch disk, clutch pressure plate, release bearing,and crank bolts. No other parts necessary. Flywheel made in USA from T-6061 aircraft-grade aluminum with replaceable steel friction surface, and hardened starter ring. Flywheel is balanced to 11,000 rpm and spin-burt tested to 14,000 rpm, SFI CERTIFIED.
