Just took my 2010 IS350 F Sport in for brake replacement (non-lexus dealership) and was told they would be fitted with genuine parts. Upon pickup I've found that they have used genuine Lexus pads, but Toyota rotors. Not only do they look different, but from what I can feel the brake performance is way down on even my previous worn out ones. Are the 350 F Sport brakes required to have a particular rotor for maximum performance? Was able to pull up very quickly before barely touching the pedal, now it's a hard push for far less response!
Cheers
