2010 R55 N14 JCW with GS6-53BG manual transmission on the dual mass flywheel.

My clutch just went out and I have been thinking about converting over to the single mass flywheel which is supposed to be on the NA minis of the same year. Ive been trying to read up as much as possible to make the best choice. There are single mass flywheel conversion kits for the S and JCW models. But if there already exists a single mass flywheel for the NW models why not just use that for a conversion? I already know why a dual mass flywheel was used and I for one care less about comfort noise and vibration levels when it comes to a car I am going to be pushing.

Are there any write ups on using factory parts out the door rather than just buying a kit? If you are running this conversion what kit are you using and how do you like it?

 

When I replaced the clutch in my 2012 R55, I went with the ClutchMasters single mass steel flywheel and FX100 kit. On my tuned N18, it never slipped. The steel version was about the same weight as the OEM dual mass flywheel, so no loss in drivability either. The FX100 clutch disc help great, but also wasn't as "On-Off" as multi-puck clutches can be.

Going with the OEM single mass from the NA cars... I would worry about the clutch holding the torque of the turbo engine. Especially since yours is also a JCW.

 

I had read your info on clutchmasters and liked what you shared. Thanks 😊

I’m older and enjoy having options when modding. I also drive diesels so clutch disc chatter isn’t bothersome. When driving I like having that connection with the mechanics, tires, earth.

 

btw how’s it holding up? How much did things change between the two clutch styles for the car and for yourself? Would you go this route again and why?

 

Sold the car, but I ran that clutch for ~80,000 miles or so on a stage 2 tune without issue. I would not hesitate going with that same clutch kit again. There were times I wished I had gone with the aluminum flywheel, but drivability was pretty good with the steel version. The FX100 clutch disc was very easy to dive and modulate, but still grabbed when you wanted it to. It never slipped on me, even when new.

 

That's a good thing to hear.

 

I’ve ordered the masterclutch steel single mass but stuck on if I’m going to buy the fx100 or fx200. Did you have your mini dyno’d and how hard did you push it on the regular?

 

Doesn’t look like they have the FX200 kits anymore:

I never dyno’d the car, but it did run strong. I didn’t regularly beat on it, but did regularly push it. That car loved the boost. I never rode the clutch, but when I dropped it hard shifting gears, it never slipped. For anyone not regularly hitting the drag strip, I think the FX100 was a good choice. Their new FX250 kit sounds like an interesting next option, too. When I was deciding on which clutch disc to go with, their customer service sales team was very helpful.

 

I called and he said that the fx300 is the new fx200.
