Agree, although the N54 in the Z4 35is is the exact same engine in the 1M Coupe'. All they really need to do is tweak the suspension and brakes on the 35is and call it M performance or whatever! Since Rahal-Letterman is running a Z4 in ALMS this year, maybe they should put the S63 in the thing until the complete redo comes along! Thanks for the input, guess I will just wait and see what happens in the next couple of months.
