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.
