Happy to report back on these. I was impressed. Huge improvement over stock. Very low levels of dust even after 4 sessions on the track. Have used Hawk and Porterfield pads before. Hawks were superior on the track but TONS of brake dust and squeal. These seem like a nice upgrade over stock for the car that does the occasional driving event. No squeal or noise. Installed on used OEM rotors. I followed the bed in instructions and the next day drove 100 miles to NHMS. Definitely heat cycled them on the first session. Came back the garage smoking. Felt even better throughout the day. Installed these along with a fresh flush of Motul RBF600 and brakes were no longer a concern. My tires on the other hand have seen better days...
