Thing is the OG M2 only needs comparatively simple mods/improvements to fix the performance 'shortcomings'. I track but am not looking for those last few 10ths in lap times (or wouldn't have ordered 6MT), I more enjoy tight/twisty mountain roads.
My BM3 custom stage 2 gives me M2C stock power, any more really isn't useable on street. Ohlins R&T improved handling/compliance & most importantly fixed the rear bottoming out/violent rebound, F80 alloy/carbon brace (incl strut top re-enforcement rings) did improve steering/turn-in, Auto-Solutions SSK/CDV delete/Turner trans mounts is almost Porsche GT good and the sound of the N55 (catted DP) going hard in forests/mountains is seriously addictive
Most of the changes/'upgrades' the G87 brings don't get over the huge negative which is the added 200kg and where would you start trying to fix that anchor on performance
