This I'd like to know because I just purchased one of these kits for my GT.
I thought Saleen and Roush both get their kits from Stoptech. The parts are identical and interchangeable except color of the calipers which is different. Could the squeaks be a function of the brake pads which are used (I believe ceramic PBR's). Also shouldn't Roush and Stoptech Kitted owners experience the same issue? And couldn't the mediocre braking distances be caused by the fact that Saleens are usually heavier and also run heavy 20in wheels?
I wouldn't be a bit surprised if a lot of these issues people experience with these kits result from not properly bedding in the brakes as the instructions for the kit demand. The factory installs the brakes and customers drive off the lot without knowing to do so.
You're right. After many service complaints, my dealership created my position, and sales reps were instructed to introduce prospective buyers to me so I could flll them in. The pads weren't so much the problem as the bedding process. The rotor and pad compound (early 05-06's) were a hard compound and did not work as advertised unless broken in. As first, Saleen would ship new rotors, and then advise me to perform the bedding process. Then they just advised to do the bedding process. 10-15 35mph to 0 high pressure stops is usually what I did to take the squeaks away. I've never driven a GT with the Saleen brake kit so I'm guessing the 20's hurt stopping distance a little. I've driven hundreds of Saleen's and yes, as they are configured, they are not worth the money.
