Stage 2 flywheel - M5 clutch conversion for 1989-1991 E30 318is with M42 motor.

Ultimate throttle response and faster acceleration at your command!

National-level race winners use the UUC Stage2/M5 clutch combo.

UUC's exclusive-design "sprung hub" clutch design Stage II lightweight flywheel has been named one of European Car magazine's "Top 10 Products"

"Stage 2" racecar technology you can drive on the street...

Tipping the scales at only 8.5lbs, this aluminum flywheel boasts the same great features as our Classic flywheel, 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 E30 clutch, so we have reduced the Stage2 flywheel weight to achieve an overall rotating mass that is essentially identical to a typical 12lb lightweight flywheel that utilizes the E30 clutch.

This clutch has several advantages for the enthusiast driver:

• Maintaining the reliability and over-the-counter availability of a BMW factory part.
• Greater clamping force than standard 3-series clutch.
• Incorporates a sprung-hub design to minimize gear rattle, includes heavy-duty steel pressure plate.
• No 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.

Because BMW specced this clutch for use on the powerful S38-series engine in the M5, it is more than up to the task of handling the output from any M42 motor, even those equipped with superchargers..

UUC customers have been using the Stage 2 & M5 clutch setup in turbo or supercharged M3s and MZ3s with fantastic results. Our own testing has shown the M5 clutch to reliably handle in excess of 450hp.

The UUC Stage 2 flywheel and clutch assembly has been used in the "test platform" M3 of Eurosport High Performance's supercharger development, reliably handling many miles and dyno runs in this powerful machine.  UUC also provides many US and European turbo and supercharger tuners with the Stage2 setup.

You can be assured not only of the performance increase you will experience, but the long-term ease of ownership that comes with knowing a replacement clutch is never any further away than your dealer's parts counter.
