ok, ive got the cobra brake upgrade finished, had em an for about 3 years now. is anyone else haveing problems with these being exessivly noisey and warping? i bought the rotors from ford and put them on brand new, and the calipers from my old cobra. ever since i have put them on they havent been "right". when i slightly press the brake pedal it sounds like the pads are going to rattle out of the calipers, are all the 2 piston pbr's this noisy? finally, what would be the next best thing above the cobra brakes? i want to replace them becouse the braking power isnt quite what i want. possibly a set of 00 cobra R disks and calipers?
