Lightweight Flywheel Kit (Performance Organic) by UUC Motorwerks

Product Description

Stage 2 flywheel - M5 clutch conversion for all M20 "i" engine models.

This package uses an 8.5lb flywheel platform with the correct ring gear for the E30 325i (and other models using the M20 i-series engine), and the complete clutch kit from the E34 M5 3.6l. Even though the flywheel weight is only 8.5lbs, the heavier E34 M5 clutch package gives the overall performance gain of a conventional E30 lightweight flywheel of around 12lbs with E30 clutch.

Direct access to the larger clutch disk size of the E34 M5 (240mm) and greater clamping force of the superior E34 M5 pressure plate for high-powered modified cars and for greater longevity than the smaller original clutch. Even when using a standard OE-replacement E34 M5 clutch, it's the equivalent of a performance E30 clutch. The E34 M5 system was originally designed for a 315hp motor in a chassis weighing several hundred pounds more than the E30.

The lighter weight flywheel gives a very noticeable increase in acceleration, particularly in the lower gears.

This package is ideal for heavy-use enthusiast cars, either for street or track use. For extreme-power turbo cars, UUC offers even higher-performance versions
of the E34 M5 clutch system in the Performance Organic, Kevlar, and Cerametallic facings.

The E30 Stage 2/E34 M5 clutch conversion package is a direct bolt-in to the standard 325 transmission. No modifications required, standard starter and clutch slave cylinder are retained. Pedal effort and engagement style is virtually identical to the standard E30 clutch.

This clutch has several advantages for the enthusiast driver:
* Greater clamping force than standard 3-series clutch.
* Incorporates a sprung-hub design to minimize gear rattle.
* Includes heavy-duty steel pressure plate.

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.

All kits come complete with Stage 2 flywheel, pressure plate, clutch disk, release bearing, crankshaft bolts, gall plate, and loc-tite.

Technical Details:
* Constructed from CNC machined 6061-T6 aluminum
* Dowel pin hole: enlarged like factory-fit.
* Friction plate: replaceable, 1050 steel (suitable for any clutch material).
* Balancing: 11,000rpm and spin-burst tested to 14,000rpm. SFI CERTIFIED
* Weight: 8.5 lb
