I didn't have the brembo version, but the regular GT brakes version and I didn't care for them. I mean the drilled and slotted rotors look cool, but I felt they did not have as much stopping power as the OEM rotors and pads. They also squealed really bad. Took them off after only 1k miles or so. I upgraded to stoptech slotted rotors with hawk HPS pads am happy with the results. Although I will be installing the 4 piston brembo's soon as I am supercharged and want the look and feel of the brembo brakes.
