Reports are in...

I installed the twin disc clutch in the BMW and it works great. The clutch is smooth and surprisingly can easily be slipped like a passenger clutch despite it having two solid friction plates. The clutch performed very well in the Enduro race with absolutely no issues. I'm very pleased.

Twin Disk clutch and flywheel technology for the E39 M5/540i and Z8

Keeping a working clutch in the powerful E39 M5 has been a problem since the car was first built. The initial design had a small clutch normally used for the 3-series tasked with harnessing the big M5's V8 torque. The result was frequent and expensive clutch replacements at the owners' expense. With the increased power levels of aftermarket tuner superchargers and turbochargers, this problem only became worse.

UUC has a solution to this problem. By literally doubling the clutch surface area with twin clutch disks, there is now an option that has long-term durability, high power capacity, and smooth-as-original operation.

Unlike other race clutches that are noisy, clunky, heavy, or short-lived, the UUC Twin Disk package drives just like a normal clutch. It can be slipped smoothly in stop-and-go traffic and requires no more leg power on the clutch pedal than the original clutch.

Packaged with a reduced-weight flywheel, a rotational mass savings will improve the car's acceleration and make it even easier to modulate clutch engagement with rpm. A noticeably quicker and livelier car is the result.

Larger surface area of a smoother-functioning material is the key to combining the characteristics of high torque capacity with street-friendly operation in this all-new design. This unique design combines the stiffness of a steel cage with the reliability and compactness of a steel cover, and maintains normal pedal effort.
Total package contains everything required: flywheel, clutch disks, aluminum cage, steel cover, release bearing, and all hardware.

Twin Organic: 850hp, 640ft-lb applications

$2,750 for a clutch? Really? You could buy a whole E39 parts car for that.

Not just for a clutch; for a complete lightweight flywheel and twin disk clutch package that will take anything you can throw at it.

For some people who drive their E39s mildly, a $400 "white box" service replacement clutch is sufficient; for those with extra power, and especially those with extreme power supercharger/turbo setups, that really use their cars enthusiastically, this UUC Twin Disk is the kind of setup required to a) hold the power, and b) not need replacing so often.

I think the percentage of 39's who can really utilize this set up is less than 1%. A ceramic puck'd disk can hold 600-700 ft/lbs, I don't think I've read of too many people coming close to that on the forums.

I bought the Lightweight flywheel and the Kevlar Clutch for my 530i, I can't be more happy!!!!
Only issue, the rattle sound, but I'm waiting my oil supplier give me the 75w140NS + MT-90 (I'm in a very hot climate)..... both are Redline oil!!!!!

UUC rocks!!!!!

Almost 20,500 E39 M5s were produced by BMW. 1% of that is still quite a few cars.

A pure ceramic single disk may indeed hold that much power... but how does it drive? How smooth? How much will your mother-in-law complain about the clutch judder and noise? What the UUC Twin Disk has proven to be in our other applications is quiet, smooth, durable, and so far in the past few days of offering for the E39, selling quite briskly.
