UUC brings M5 clutch technology to the E30.

[Rob@UUC]

Great news!

Our famous Stage 2 lightweight flywheel / E34 M5 clutch conversion package for E36/E46 has now be configured for E30 compatibility.

This package uses our 8.5lb flywheel platform with the correct ring gear for the E30 325i models, and the complete clutch kit from the E34 M5.

Even though the flwheel 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.

Why is this a big deal for the E30 community? You get the larger clutch disk size of the E34 M5 (240mm) and greater clamping force of the superior E34 M5 pressure plate. 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. Rev-matching and heel-toe shifting are also much easier.

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 our Performance Organic, Kevlar, and Cerametallic facings.

Our 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.

Pricing for the complete package (flywheel, pressure plate, clutch disk, release bearing, mounting hardware) starts at under $1000. Components are in production now.

to confirm. this is a direct bolt in kit for the getrag 260 from the 325i e30?

im liking the look of this. awesome!

[MR 325]

Very nice! Great option for US turbo guys who won't want an annoying 6 puck.

wonder if this will work with a e46zhp/e90 ZF 6-speed ...

Yes, the Getrag 260...

Those two 6-speed transmissions have a different input shaft spline design (22-tooth triangle, versus the 260's 10-tooth rectangle). We can offer you a version that will work with that 6-speed.

Definitely added to my wish list.

So you have trouble keeping up with the demand for the products you currently sell so you are designing and selling new stuff while people are still waiting to get the parts they have ordered months ago...

UUC's backorders are actually quite rare these days. A recent backorder on a few shifter and DSSR components was due to an unanticipated fabrication equipment issue, since resolved and now back online, pumping out parts for all of those orders affected.

Not all parts are made on the same machines, of course. The CNC lathes that turn the 1.5" diameter shifter components are not the same machines that turn the 12" flywheel disks.

so what are these rated to tq wise?

[Rob@UUC]

so what are these rated to tq wise?

That varies by clutch and torque ratings should only be considered next to usage style. I'll explain each one below, but then reference a hp (not tq) number because that is typically how gas-engine comparisons are made or capacity listed.

I stress this as much as possible: choose the clutch option based primarily on your usage style. Don't go for "the most badass" just because you can... it may not be the right part for your requirements!

For example, an OEM "service replacement" regular M5 clutch can comfortably support 400ft-lbs in a street car with street tires that is not driven abusively. Same clutch that I ran in my E28 turbo street cars 300hp and 475hp) for years. But that's very different from a car that sees a lot of dragstrip or drift use, or that uses sticky track tires. Nevertheless, for long-term durability under a variety of conditions, we recommend the OEM M5 clutch for applications up to approximately 350hp.

Leveling up, our UUC Performance Organic has been reliably used in cars in the 500ft-lb range. This clutch is ideal for the very powerful street cars that likewise are not seeing frequent drag race or drift use. This clutch has engagement and durability characteristics just like the OEM clutch and is recommended for applications up to approximately 450hp.

The UUC Segmented Kevlar is a new generation of kevlar design, a continuous face with high-pressure scalloped zones that allow it to engage smoothly and avoid the glazing issue typical of other-brand kevlar offerings. Max torque range is around 550ft-lbs, but the nature of the material makes it more suitable for frequent harder use. Again, for long-term durability, we recommend this option for applications up to approximately 600hp.

The UUC CeraMetallic option is designed for the extreme/abusive requirements of high-power drag racing and drift use. Another engineered design, it features a continuous backing plate but separate pucks of material around the face. Engagement is somewhat more abrupt than the options above, but this design will take a pounding in hard-use requirements beyond 600hp.

Would this fit my S54, 6 speed conversion?

As you've got an all-E46 M3 setup in your car, you would use the E46 M3 version:

I'm running the e36 spec version of this clutch. Drivability is equal to oem, and man does the engine rev fast with this flywheel. My only complaint is that the flywheel is quite noisy at low RPM, <2000rpm.

Excited about this. Sent you an email Rob.
