M3 ZCP = FAIL
UNLESS------> M3 ZCP faster than RS5
BMW maybe did not want to spend much money on making the M3 better, and ZCP was enough to improuve M3 for little money and still make it better than C63 AMG and RS5.
But I think they still could take some other parts from the M3 GTS:
>BMW Performance seats in M3 style
But I remember the interview with the boss of BMW Performance: maybe they are preparing some parts as for example:
>carbon intaike with KN filter (as there is for X30i E8X/E9X)
>carbon parts (mirrors, lip/splitters, diffusor, spoiler, interior trim)
>gloss black trim
>short-shifter-kit (for 6MT as there is for X30i and X35i E8X/E9X)
>lightweight front seats
Well we'll see.
