I've put a few hundred miles on them now. City, highway, and spirited driving. First impression was favorable. Brakes were far more responsive (not surprising with the increase in torque). After they were broken in, the initial bite wore off slightly, but the brake feel is much more progressive and linear. Noticeable decrease in braking effort with the same result. I actually feel like I can activate the ABS/lock up my 275 UHP summer tires on dry pavement. Never got close with the OE size brakes.
