Any opinions on these? I am doing a conversion and I have a 95 M3 Tranny. There is someone that is offering me a UUC Flywheel Brand new and never installed.



I am not really planning on tracking the car, but I do want the performance feel. It is mostly a summer car for me, and I want to get everything done right. Please help me out as I need to let this guy know today. I am getting if for $575 Cad shipped.

You will need the special (expensive) M5 clutch and pressure plate for this one. This isn't a cheap upgrade but the car will rev better.

It all depends if you are willing to spend more than 1300 Cdn to get your clutch done.
It is a good price non the less, but keep in mind that you need a special clutch.

Bruno, how much is the clutch kit for this then?

09-01-2005, 10:38 AM
Might be a stupid question, but its marked: USE US-SPEC E34 M5 PRESSURE PLATE AND THROWOUT BEARING.

Are the stock flywheels the same between the E36 and E34 ///M models?

If its UUC Stage I kit, you will need e36 m3 clutch.
If its UUC Stage II you will need OEM e34 m5 clutch(cheapest solution) or you can get SPEC clutch for E34 M5(there are 3 stages of spec clutch)

Ital 325i, clutches are different.


pictures just loaded, and it is Stage II.
You will have to get e34 m5 clutch

You can get a M5 (e34) clutch kit on ebay for $288 USD (includes clutch, pressure plate and throwout bearing)

So is this a good thing to put on my car??? I am going from auto to manual, and I want to make sure that I do it right the first time. There are a lot of guys on this board that have done some mods on their car, and I don't know too much about how this will affect the ride and performance of the car.

You have to be careful as there is two types of E34 M5 clutch, and UUC do specify to use the one type that is hard to find, even my suppliers contacted Sach and Sach told them it was discontinued... Not sure where UUC gets them.

From UUC:
pressure plate,
throwout bearing
& clutch used:
'91 - '93 E34 M5 parts required.
BMW part # 21 21 2 226 428 (complete clutch kit)
VERY IMPORTANT: some parts vendors have been
supplying the wrong clutch components. We strongly recommend sourcing the
entire flywheel and clutch from UUC to guarantee you get the correct parts.

Specify Sachs part number KF777-01, do not accept substitutes!
Pressure plate should be marked "3082 147 (238 or 208)"
Incorrect pressure plate will not work - verify before installation!

Like bruno said. make sure you get the right parts...

Otherwise, yes a ltw flywheel changes the dynamics of your car completely. Your engine will rev smoother and considerably faster.

The downsides are as follows:
- may experiance a rattle at idle

Are there any other reccomendations as to what I should put in and where I can get the parts?

Do it if you have the cash and can live with a bit of transmission rattle (some thicker transmission fluid can cure it).
For the parts, you can get the clutch from UUC.

It is all about money at the end...

Well thanks for all the info. Just spoke to Charlie yesterday and it looks like he is running the same setup in his M3. So I purchased this Flywheel today, $476.00 U.S. shipped to my friends house in the Michigan. Charlie is going to get me the clutch, and my seals. So it looks like I am almost ready for my conversion in the spring. Just need the shifter, which I am debating on getting the Whalen. Saw it on Mitch555's car and it looks pretty sweet. Thanks for all of your help guys!

I just got this kit installed. I purchased the kit from UUC, and all the shifter bushings, tranny seals, fluids etc... from Bruno. I love it, the car feels much less restrained. I used Redline MTL and I do not have any rattle (had some for the first two days or so). I love how much more aggresive the car feels, and I get better gas mileage which is nice since we are paying as much as $1.42 now here.

Sweet!! good to hear that it is working well in your car Duffy325, and that you have a 325 like mine. I am extremely excited to get my car on the road with the new 5 speed conversion! I will make sure that I keep everyone updated with pics and progress!!
