What is this flywheel

[PA_Welder]

Bought this "JB racing" flywheel on eBay on very little information when I got it I realized it wasn't a JB racing flywheel. I tried to look up information on it but cant find anything. Any help determining if this is a m20 or a m50 flywheel and any other information about it would be greatly appreciated. The number on the flywheel in the bototm pick looks like it says 50-071.

By the look of the "F1" i'd say it's probably an F1 flywheel. People seem to like their clutch kits for the e30 platform.

You could measure the friction surface to see if it's a 228mm or 240mm. That's a pretty easy way to get an idea of what it fits.

Might be a fidanza flywheel? or FX/F1 racing/gripforce?

Yes that is what I thought just when i looked it up I haven't been able to find much information on it

[PA_Welder]

Sorry didn't see your last post i measured it and it was 228 but from my understanding both m20 and m50 have that sized friction material

Might be an early JB racing as well.

m5x and M30 are 240mm clutch disc, so it's not one of those.

Best way to have a better idea is to compare it to an M20 flywheel.
