Does anyone know if an e34 m5 clutch will work on a 535i?

[AllanS]

I'm looking at clutches and the m5 seems the cheapest, for what you get at least. But no one seems to know if it works on a stock dual mass flywheel on a 91' 535i.

Thanks,

E34 M5 does not run a dual mass flywheel. The springs are on the clutch disc. You might try an e28 535i flywheel with an m5 clutch. That might solve your problem.

Do you think an e34 m5 flywheel will work with the 535i, or am I stuck with some combination involving the e28 one? Will an e29 flywheel work with just an e28 m5 clutch, and nothing else?

I may go with a spec clutch... the dual mass isn't really a problem right now.

Personally I thing just going with a stock 535i clutch is the way to go. The dual mass units are heavy and make a ton of noise as they wear. I have been running an e28 clutch for a number of years now and it performs like a charm.

or swap in an automatic...:D

I bought this car to get away from an automatic, actually :)

My clutch right now is solid, but I haven't pushed the car much yet, due to crappy weather here in NY, so I haven't noticed any slippage. But I'm assuming that the stock clutch isn't going to like 300hp/300ft/lbs torque, which is my goal. I don't really know what to do.

Thanks,

There is a heavy duty version of the clutch made by sachs. Korman BMW sells them. You would run a stock e28 flywheel with a heavy duty clutch, I think you will be fine. Biggest factor to remember is that before you get on the gas hard that clutch need to be fully let out. If its still slipping and you put lots of power to it - it will not live long.

[AllanS]

Thanks for the info Derek, I guess I should give Korman a call. Do you think it'd be worthwhile to try metric mechanic too? He/they are the only other korman-like place I know of, that still supports older models at least.

You might be able to call BMW and find the heavy duty clutch kit there. There are a number of salvage yards to buy a flywheel from. I would go Korman before I go Metric Mechanic.

Hi
Just singned up to the site.
I have been wondering about this mod for a long time.
does it all just bolt up , flywheel bolt pattern is 100% the same.
and the e28 535 clutch is a perfect fit on the e34 transmission main shaft on the transmission .
last question do you need the shift fork and slave cylinder off e28 or e34 parts work.
any info appreciated.
thanks
My dual mass flywheel sounds likes its about to explode.

i called rob from UUC just a few days ago and we were talking about this.
the best route to go is

m5 flywheel (lightweight from uuc)
and m5 clutch with sachs pressure plate

it'll give u a lot of options in terms of power
in the future, and will really wake the m30
up with that light flywheel. the current 35lb
dual mass that we have is just stupid. plain
stupid.

[Derek A.]

The uuc stuff is great. But you are going to have about $1500 in a flywheel/clutch setup. A stock e28 535 flywheel is about 24 lbs so it is a substantial change from the factory 32-35 lb unit. If you go to light in the flywheel it does make the car difficult to drive off the line. Given that the e34 is not a lightweight I think the stock e28 setup is really the way to go. Quiet, good grabbing power and improves the overall driving feel of the car with out having to rev it to 3000rpm to try and get moving from a stoplight.

Thats what Im saying $1500 is a lot of coin. too much really.
So Im guessing thats a yes that
all the e28 parts bolt right up ( flywheel, clutch, clutch fork and e28 slave cylinder or do I keep the e34 slave cylinder and clutch fork
really looking for a definate answer.

If anybody is interested the e28 flywheel can easily be lightened to
18-19 lbs and is still 100% reliable never had a problem just find a good machine shop.
it made a huge differnce on my turbo e28 incredible difference. saves a lot of money compared to uuc prices and the stock 535 clutch can handle a lot
of abuse even with a turbo.

please let me know details on the e28 flywhell and clutch into
a e34 535 .
thanks

All you need to change is the e28 flywheel and use the stock e28 535i clutch kit in the e34. Everything else is the same. Of course if the car has high miles on it - change the plastic pivot pin and the clutch fork. Hydralics stay the same. If memory serves you need to use the e28 bolts as the e34 ones are longer.

Thanks derek
thats good news .
I have all these parts sitting in my shed
ready to go. Its going to be nice not to hear the rattle of that shitty dual mass flywheel anymore. I already have my flywheel shaved down to 18lbs
ready to go. I cant wait to see the difference in engine responce.
Thanks again
