How many miles ore on your current clutch? My 05 MCS JCW have almost 100k on it?

I was going to ask the same thing as Dave. I have 148k on my mini still the original clutch. I am planing on putting a Valeo in it soon. I have installed one in a friends R53 and I really like it. I drive very spirited and am sure the Valeo is all my R53 needs. As fair as noise goes I thought the Valeo was just as quiet as the stock setup. Also my duel mass flywheel makes lots of noise, I can't wait to get rid of it. Also the single mass is much lighter. Is your clutch slipping?

Anyway, under normal driving the problem isn't noticeable. However, under hard acceleration at speed (such as getting onto an expressway) the tach will swing wildly back and forth and if you continue for a bit there is the smell of burnt friction material. It also has the Chewbacca groan when engaging the clutch from rest. This is my 8th vehicle and none of them have been automatics. Of the previous 7, I've replaced 1 clutch (on an Isuzu Trooper at ~140,000 miles).
The first 2 years or so of Gen 2 JCW's do seem to have a higher than normal incidence of premature failure; 2009 and '10. It doesn't seem to be epidemic, but it does happen. I think 2011 is where the N18 engine starts and it appears that they don't have the issue. By the way, the 2009 and '10 engines are the N14 and the clutch diameter is 228mm. The N18 clutch has a diameter of 235mm. Interesting...
I will be talking to a distributor for OSGiken tomorrow as I'm leaning towards the GT model with the "soft diaphragm". The rating for those gives a good safety factor over stock and that should translate to longer life. Feel and pedal effort evidently are close to OEM, which is a consideration to me.
I have not noticed any problems specifically related to the dual-mass flywheel. However, that will be one of the discussion topics regarding the OSGiken. A single-mass flywheel is an integral part of the package and I understand that some people experience increased noise when using the clutch. -

Buy a JM Turbo coopers solid flywheel and clutch setup. period. The OS Giken is a race part and as such street durability is questionable. The first one we installed had a disc worn to the rivets in 15000 miles. That customer insisted on another, and it was gone in 16000 miles. We then put in the JMTC and after 30k it continues to work nicely. The JMTC stuff is very nice, lasts long and feels great. We are installing another one today. I have installed and then subsequently removed two other OS Giken units due to noise, overall crappy feel and premature wearout.

50K is way early for a clutch but then again it is a second gen. I have a friend that had 3 clutches done under warranty by MINI under 50k miles so anything is possible.
With OS Giken you should be good to go. -

IF you have to have one of them, like the two customers who paid me to install then remove them, expect ZERO customer service after they take your money.
We have installed DOZENS of the JMTC clutches, fantastic customer service, nice parts that WORK for reasonable money. -

I'm confused. You said "worn to the rivets", but they bond. They don't use rivets as I understand.

Im trying to save you the grief and expense of replacing that thing twice-search my other posts on clutches to see why yours is slipping-the dual mass flywheel is failing and killing the clutch. IF you install an OS Giken clutch in an R56 series MINI, you will get to do it again. -

I suspect that a considerable part of the problem can be put down to technique. You don't drive them like OEM parts. I've adjusted to some pretty different cars in my time, so this doesn't bother me that much.
However, there are no guarantees with anything. My original clutch actually started going at 40,000 to 45,000. It's only because I have been extra careful that I'm close to 51,000. Do I expect miracles? No, I don't. But I do know that aggressive driving kills the OEM parts quicker than race quality parts. -

I think people destroy the OS clutches because they dont know how to work a clutch.

Sounds like most every IT department with which I've ever been associated: Blame the user loudly and incessantly to distract folks from noticing poor design or shoddy execution [emoji41]

Well, except in some cases it is true.
