I did it! Lightweight Flywheel and Stage 2 clutch

[Max Impact]

I recently sold my 2000 BMW M Roadster with 80k on it and the stock clutch felt as good as new so you could imagine my disbelief when the 2001 M Roadster I purchased with 18k on it had a bad clutch. Come to find out BMW used a less robust clutch disc starting in 2001, makes since no need for a heavy disc in a car with just 75 more hp right? Anyway after going around with BMW NA over this idiotic and obviously flawed decision and getting nowhere, I decided to do handle matters on my own. The subject of clutch replacement is very vague at best on most of these threads so I started making calls to some of the best independent BMW specialists around NC. The winning recommendation was a complete clutch kit from Bimmerworld featuring a JB Aluminum Flywheel and a stage 2 Kevlar clutch disc. I ordered the kit $1299.00 ouch! and had it installed this past Monday at Carr Industries in GSO, another $600.00 ouch again! but these guys are very good and did their best to cut me a few deals on some other things I had done while they did the job. Now I must drive the car a painful 500 miles without high rev shifts or clutch braking, bummer! but I must say that the clutch pedal feels great maybe a little heavier than stock but not much at all. As far as the supposed drive train chatter that comes with a lightweight flywheel, there is none, if there is its so light it cannot be heard while sitting in the car. Engagement is flawless and super smooth at low revs, won't know about high revs until after break in period. I can however tell a difference in engine responsiveness already and can't wait to give her full power to see what happens. I’ll keep you posted......

That's actually the clutch kit I would've recommended to you. The flywheel is like 10 or 11.5 lbs, ya?


Everything sounds good. If you feel like you've got some time on your hands after you've been through the break-in process, writing a review of this kit in our product reviews section could be very helpful


Oh, and welcome to Bimmerwerkz

Yes, it weighs just under 10 pounds compared to 25 pounds stock. According to my track rat friends for every 1 pound you remove from the flywheel = a 20 pound weight reduction of the car as far as acceleration is concerned. So if this holds true a $500 to $600 lightweight flywheel would equal the best dollar for dollar performance increase. Hopefully it won't take long to break it in, I have plotted a long course on residential back roads and plan on driving it almost every morning to speed things along. Will give full review once its done.....

Cheers!

^^ Cool. SOunds like a nice setup. Hehehe -- I think I would have manufactured a quick break-in plan also, if I were in your situation.

That review will be greatly appreciated.

And welcome back to werkz

This is true under N/A and Supercharger circumstances, but in turbocharged cars it's a countermeasure to building boost.

Just pointing it out so you don't believe all that your "track rat" friends say
