Kit includes B11 flywheel only for M5/Z8 V12 clutch conversions.
For use with E31/850CSi clutch only.
The UUC flywheel is the heart of the V12 conversion, perfectly
adapting the V12 components to the V8 transmission. 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
V8 flywheel/clutch package, acceleration and throttle response is
noticeably improved. This is truly a "no compromise" design, the way
the V8 cars should have been equipped by BMW.
Supercharged M5/Z8/540i cars have been equipped with the UUC Ultimate
V8 flywheel/clutch combination with excellent results.
