lets say the RF-C will all "fluids" etc is exactly 3,900 and the M4 say its 3,500 like you say. Its still 400 pounds AND don't forget how much better the M transmission will be
The M4 will outperform that new lexus. I'll take that bet.
As others have posted perhaps not quite at succinctly, the likely power to weight (weight to power...) ratios are:
3550/450 = 7.9 lb/hp
3850/480 = 8.0 lb/hp
That is less than a 2% difference. The 300 lb will give the M4 some significant handling and braking advantages. My prediction is that the cars will be basically a drivers race in a straight line. However, pretty well all of the journalists test metrics will have the M4 edging out the RC-F. The margin of victory will be wider on anything twisty.
