More potential for spun crank hub, for sure . I think B58TU actually will be the better option, not sure what MY that shows up in.
Crank hub definitely a concern if you go big on tuning like stage 2, etc. Next gen M2 (G87) will have S58.
I've read that the crank hub issue affects less than 1% of S55 engines. I'm considering a stage 1 Dinan tune to M3/4 HP- I can't imagine that would get remotely close to spinning the hub.- anyone have experience with it? Perhaps I should take the question to the M2C forum...
