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". Tipping the scales at only 8.5lbs, 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 clutch disk, pressure plate, and throw-out bearing from the 3.6 liter E34 M5. The total weight of the M5 clutch disk and pressure plate combo is greater than that of a stock E39 5-series clutch, so we have reduced the Stage2 flywheel weight to achieve an overall rotating mass that is essentially identical to a typical 11.5lb lightweight flywheel that utilizes a standard E39 clutch. This Cerametallic clutch option is intended for high-power cars fitted with a turbocharger or supercharger up to 550hp. Engagement will be more abrupt and not as smooth as our Performance Organic or Segmented Kevlar options. 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. Because BMW specced this clutch for use on the powerful S38-series engine in the M5, it is up to the task of handling the output from a modified 3-series motor. UUC customers have been using the Stage 2 & M5 clutch setup in turbo or supercharged E39s with fantastic results. Our own testing has shown the M5 clutch to reliably handle in excess of 450hp. Kit comes complete with flywheel, clutch disk, clutch pressure plate, release bearing, alignment tool, gall plate, 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.
