To answer your question... A popular combination for an aftermarket clutch and flywheel setup is the ///M5 clutch and UUC lightweight flywheel. They claim it's great for daily driving, but it's a lightweight flywheel that weighs 1/3 the weight of a stock flywheel (8 lbs.). Your car will rev fast, rev hard, and the clutch will probably grab something fierce. Another one I've seen tossed around is the Gripforce clutch and flywheel combo. I believe their flywheel weighs roughly 16 lbs., so it's not as difficult to drive, but it's still going to be completely different than what you have now.

Then again, if you just want an OEM flywheel with the ///M5 clutch, you should be fine. I believe the clutch will feel significantly heavier and grab much more firmly than what you have now, though.

Let me tell you with my experience on my gripforce stage 2 clutch. It is stiff as ****. Probably one of the stiffest clutches I've ever driven even more than a Ferrari testarossa. But it does grip like a mfer.

Yes, it will work, but... why are you getting a used clutch?

Read this: http://forum.e46fanatics.com/showthread.php?t=221401 - It will prove informative.

The E39 M5 has a V8, NOT an I6....everything is different. You would need a clutch from the previous generation E34 M5, which had an I6 engine....
Stay away from those 8-pound ultra-lightweight flywheels, there`s a good reason why they`re labeled "For Off-Road Use Only".

A Gripforce Stage II with the solid billet 16-lb. `wheel would be your best bet....the kit (clutch, flywheel, T/O bearing) can be had for around $500, a stellar deal.

If I just told him to get an E39 clutch, I apologize. My brain registered what he typed as E34.

And 16 lbs. sure would be easier to drive than an 8 lb. flywheel, but it still seems like it would be a bit more challenging than the OEM 25-ish lbs. Am I wrong?

Because you don't have 800 WHP. A Stage 2, in my eyes, is pushing it (going off what Malibu says). A Stage 1 would make for a better daily driver.

SPD is correct. Stage 1 is great for daily driving. But I had to get a stage 2 in order to support the power and driving style of my bimmer. I knew a stage 1 might be ok but for how hard I drive the car it wouldn't hold up as well as the stage 2.

No....the stock (dual-mass) `wheel only takes the self-adjusting clutch, a solid-billet `wheels requires a sprung-hub clutch, which is quite different.

Just get a Stage I setup and be happy....people say the Stage I feels just about identical to a stock unit.

Does your car make 400 WHP? No? Get a Stage 1 at the most.

Read this for a bit of educational material: http://store.uucmotorwerks.com/share...3&Refresh=True

A simple organic disk will handle a wide variety of use - including street use, auto-x, and even true racing. In fact, SCCA ITS racing rules require a standard OE-spec organic disk. UUC has tested organic disks to reliably handle up to 475hp in long-term street use. M3s regularly run through several auto-x seasons without problems.

A kevlar disk is a good choice for a heavily-tracked or road-raced cars, especially with forced induction.

Carbon/ceramic should be left to high-power cars that see lots of drag racing, or are dedicated track/drag cars.

Sintered iron clutch disks are strictly for endurance racing.
You don't need to go buy the most expensive Stage 84 clutch out there just because you want one. Malibu's car is supercharged, meaning it puts down some significant power. He needs a clutch that's able to hold that much power when he's really romping down on the throttle. Your car, a 325i, doesn't need something like that. Your car will probably never see past 200 WHP (just being realistic), so there really isn't a need to get a Stage 3 or Stage 4 clutch.

The only reason I have a stage 2 though is because my car is supercharged. You don't need a stage 2 for a stock engine at all.
