Now, I couldn't write a scathing report of a Hawk pad and not present the fact that I'm mostly pleased with a different product they sell. I also purchased DTC-60 pads, which are a race compound. You should not put these on your street-driven car, because they will not operate at a low temperature range (the range they'll be in at the just about every red light you come to..) I installed these on my front brakes only. With some additional cooling from the ducts I made, they lasted the entire weekend, and they appear to have enough material to last a good way into another weekend. They performed well, although with some fade late in my first session, when the car didn't have the ducts installed. The pads wore evenly throughout the weekend, and my rotors are quite smooth... they are ready to accept a new pad of any material. So you can change your pads at the track and not worry so much that your rotors will be a mess when you go to put your street pads back on. I can't really guess how these would have performed or held up over the weekend without the benefit of cooling, so my next task will be to see how OEM pads hold up when they are kept cool. The DTC-60's cost about 2 1/2 times what the OEM pads do. If I can get a full weekend of life out of the OEM pads, the OEM's might actually be the best option. Overall, the DTC-60's are much easier on the rotors, which means I won't be spending another $100 for a replacement set of rotors anytime soon! (STREET/RACE pads/rotor wear on the left, DTC-60 pads/rotor wear on the right) This pad compound was evidently also affected by a manufacturing/production issue at Hawk, where all the pads shipped were the outer pads. If you have bought these, or if you intend to, be sure to check before you install them that you have been provided inner and outer pads. They're different.
