Came across this old thread and I just like to say that let's not forget that both of these cars are running much stickier tires (Michelin Sport Cup) than the standard M3, which came with Pilot PS2s.

Tires are one of the biggest factors in changing a car's performance. I think it would be more fair to compare the standard M3 with sport cups against these two if you're going to compare their performance differences.
