I just ordered today a M-Sport with adaptive M suspension. I've seen a number of forum members that have gone with the H&R Sport springs. Looks great. I'm considering those or even the less aggressive H&R OE Sport springs. I'm not too concerned about a rub, especially with 235 fronts and 265 rears. I'm a little more concerned with stressing the adaptive dampers and the ride.
I'm taking ED. I've got like four months to obsess over it!
