M3 Clutch And Flywheel

[theruss1an1]

This message is for autotechnica and for those of you that know about this topic. I tried sending a P.M. but it didnt work..

I noticed you have a m3 clutch and flywheel. I got a 325is and my clutch maybe going out, not sure. Im going to have a shop check out my car in three days to tell me whats up. I have a few questions about the m3 switch over. For the clutch I found kits for about $285 that come with the preasure plate, disc, and the bearing. The slave cylinder is another about $60 on top of that. Is that all I need for the clutch switch over? You have a light weight flywheel too. Did that just bolt on the spot of the old one and also is there any mojor noise from it. I was lookin at the rogue engineering ones. I heard good things about them. How about using a stock m3 flywheel on my 325.
You got a real clean ride man. Im loving it. Very nifty mods. Hope to hear back from you soon. Thanks.

M3 flywheel fits nicely and is a good improvement. Anyone who's driven my car loves the modulation and the awesome feel you get with it. Super easy to get a good launch with it and it hooks up really well.

You could get a ltw flywheel but you just have to make sure you buy the clutch disk and pressureplate meant to work with the flywheel.

The slave cylinder isn't needed with the m3 set up, if you're short on cash you can skip that till your next pay check. The engaugement point will be lower to the floor with the 325 slave cylinder.

Thanks a lot.

One more question: IF my clutch is going out and I gotta replace it, where is the best place for me to get a stock m3 flywheel from? And also should I get a 95 set up or later? 95 makes more sence. But Im not sure.

Also is it true that the stock 325 flywheel is around 25 pounds and the stock m3 is about 10 pounds lighter than that?

Thanks,

96+ parts have a stronger pressure plate. Find a flywheel from someone selling on on Ebay or around the forums. Buying one new is pointless as you might as well get a ltw flywheel for the same price.

True,

Thanks.

Basically the 96+ M3 pressure plate can take more heat and it's stronger. The flywheel is single mass (lighter) as opposed to the '95 dual mass which is heavier, you definitely want the 96+ kits.

The slave cyl will makes depressing the clutch pedal easier (required on 318's), it's something I would definitely recommend swapping. I'm not sure if it's required, but might as well replace parts with the M3 pilot and release bearings.

Aftermarket LTW flywheels will bolt right on to the stock M3 pressure plate and disc, the swap should be quite straight forward. You can use the same release fork so don't worry about swapping that.

If you're going for the LTW flywheel, I'd recommend buying a performance clutch kit which includes better gripping compound cluch disc and stronger pressure plate. RE makes a great flywheel. I'm using Fidanza which is also the manufacturer of UUC and many others.

You will have to change your driving habbits. If you like putting the gear in neutral at 4000RPM when you stop at a light, you won't like the LTW flywheels. You have to let it off gently and sometimes even give it a little gas on neutral to keep the car from stalling. There is a slight increase in noise, some people get extra vibrations, some people get ticking or buzzing noises. I guess it all depends on the kit.

Anyways, good luck!

Thanks a lot for the help guys.

I got one more question... lol. Would a stock m3 clutch system work with my stock 325 flywheel?

No, it won't work with the stock 325 flywheel.
