"Moderate lightweight" flywheel and clutch combination for the 1993-1995 E34 540i provides reliable clutch operation without excessive weight reduction. Excessive weight reduction causes the dreaded "transmission chatter" (also known as "gearbox rattle" or "rollover noise").

With the "moderate lightweight" flywheel, a significant performance improvement is still realized but with minimized gearbox rattle... and all at a reasonable cost!

PRICING OPTIONS (complete kit including flywheel, clutch components chosen, all hardware, ignition timing plate):

The design of the "moderate lightweight" flywheel and clutch for the BMW V8 had to combine all of these characteristics:

• 13.5lb reduction is flywheel weight for faster acceleration and better throttle response.
• No change in clutch feel or pedal effort.
• Clutch features "sprung hub" center for power pulse variation damping, an additional noise reduction technique.
• Quiet operation with minimal gear lash sound.
• Power-handling capabilities suitable for the original rating of the 540i with options for greater power levels.
• Readily-available replacement clutch offerings.

THE CLUTCH:

The clutch is from the well-respected and race-proven line of UUC performance clutches. The "Performance Organic" disk proves normal original equipment clutch feel and smoothness with added power capability. The "UltraSmooth CeraMetallic" is designed for the "warmed up" 540i or for more "enthusiastic" drivers.

In addition to the improved materials and design, this clutch features a sprung hub center section that damps the power pulse variations that cause transmission rattle in standard fixed-hub clutches. Combined with the specific weight of the UUC flywheel, the result is a lightweight flywheel/clutch combination that is rattle-free in most installations (variations in transmission wear, condition of fluid, and other factors may cause some cars to experience very slight rattle).

• "Performance Organic" clutch kit with performance clutch material, pressure plate with even greater clamping force. Rated beyond 500lb-ft.
  
• "Segmented Kevlar" clutch kit with higher performance clutch material, pressure plate with even greater clamping force. Recommended for harder use or those with greater power modifications.
  

THE FLYWHEEL:

Built with the same level of technical sophistication and quality that earned UUC a European Car magazine "Select Gear Top 10" award for best products of 2003, and also the SFI race-spec certification, this is simply the best quality flywheel that can be built. Construction details include CNC machined 6061-T6 aluminum disk with replaceable 1050 steel friction surface (suitable for any clutch material, including race-only sintered iron). Friction surface retaining bolt pattern is computer-designed for optimum strength and load-bearing. Correct V8 starter ring and ignition trigger ring for perfect operation.

HOW WELL DOES IT WORK?

It works flawlessly. Clutch effort is identical to the original V8 clutch, and feel is even better. With the specific weight and sprung-hub clutch design, typical transmission rattle is dramatically reduced or even nonexistent in some installations. With a significant 13.5lb weight savings in rotating components compared to the original flywheel/clutch package, acceleration and throttle response is noticeably improved.
