That might be true for the brembo but stock Pirelli's for the regular GT are complete crap. The 235 all seasons broke loose like no other. I was in complete shock that ford put those on a 400hp car. I changed them within 2 months. Although they will be going back on once the temp stays below 32 or snow is in the forecast.
Sure, but what the OP has, and what we're talking about, are the OEM "MO" Brembo Pirelli tires.
FWIW, did you expect something different from all-season tires? If what you wanted was the traction and handling, you should have popped for a Brembo car, and eaten the big tire costs.
