I have 3No 2WD cosworth flywheels

The first is the original one off my car, i had it skimmed but it didnt come up that smooth, apparently where it has got too hot from clutch slip the steel has hardened?? Some people have said it'll be fine?? - £25

The second i brought off ebay from PJ Motorsport requiring a skim, it has quite a deep groove but i was offered a better one so didn't bother with it in the end - £20

The third one is in good nick, recently skimmed - £50

I'll get some pics up later on today
