I'm not discounting the fact that it could be the rotors (it's so bad I've since switched back to the stock rotors), but just curious as the pads are an easier/cheaper fix.

I've read elsewhere that the Carbotechs seem to lend themselves to a lot of pad deposit, which may be the cause of the judder.
