E34 m5 clutch on m30?

[indierthanthou]

Is this possible, and if so, what is required?

i've got a e34 m5 clutch and flywheel in my 633 project bolts up just fine, the m5 runs a 11# single mass flywheel and normal sprung hub clutch, where the e34 535 and pretty much every other bmw designed after 91 has a shitty twin mass flywheel that weighs a ton and rattles when it gets old, and bolted to it is a solid hub clutch, the take up spring action is built into the flywheel (why it rattles when old) to change it to something better you just need a flywheel and bolts and the clutch kit, a m5 (e28 or e34) clutch should bolt up to any m30 single mass flywheel, e28 535 and 533, e24 633/635......... if you don't want to spring the extra $50-75 for a m5 clutch a e28 535 clutch can take it's place and handle just about anything short of forced induction

ok great. now will an m5 clutch bolt to a 535 single mass flywheel, like this one-
lightened aluminum flywheel
It wont let me link directly to the e34 535 flywheel page, just click on JB Racing lightened aluminum flywheels, it should be the second product down

instead of paying a assload for a aftermarket flywheel watch ebay like i did, got mine with a used up clutch and all hardwear for 105 delivered and it's the same weight they list, i think the 533 flywheels are around 15-17# which isn't bad considering the stock e34 unit is around twice that

ok...after a search of the archive, i saw that several put an e28 flywheel and clutch on their m30. what else from the e28 would I need? just the flywheel, clutch disc and pressure plate, or will I need the t/o bearing from the e28 as well? BMA has a kit with plate disc and bearing for <$300. Where would be a good place to source an e28 flywheel? ebay hasn't got too much to go on, and no e28 or 535 flywheels.
