Is the kit brand new? does it have a manufacture/packaged date on the box? Im curious too, if they are decent and cheap they may be good for 'drive home' pads. beware of the clicking with that kit. Ive had it on both the ones ive owned. It sounds like someone flipping though a stack of business cards or a wheel bearing on its way out. (not the standard slotted rotor tick)
its super annoying. I was selling some ae86 parts to a guy last month and it came out in conversation that he happened to be a Stoptech engineer, so I showed him the sound and he said that its the 2 piece floating rotor thats ticking because "the springs had heat cycled so many times." I re-torqued the rotor bolts to 6inch lbs and it didn't go away. : /
Then, after doing a few track days in a row last month the sound vanished.
Why? Do you know what these pads are?
