M2C turns in better, chassis more composed vs OG M2.
About the seats OG /M2C, the OG's are alright but on trackdays I prefer the M2C seats. They subjectively look better and with my lower back 'problems' I find the M2C seats just 'better'
Looks are subjective and I loved my LBB OG M2. 437M are nice wheels. Still an eyecatcher OG M2.
Strangely when riding behind my own M2C the last thing I noticed was the cow udder. Not kidding.
S55 vs N55 I won't go into that , just stating N55 sounds the best. And that's it
Cheers
