Hello all, I am new here. Just picked up my 2017 IS350 F sport rwd a few months ago. I've been reading on the forums for a while and it seems the F sport brakes wear down very quickly and I have seen people reference switching them for the non F sport rotors and pads. My question that I have yet to be able to find an answer to is are the non F sport pads and rotors really that much longer lasting? I mean realistically how many miles could I expect to get on non F sport brakes? I'd rather stay Lexus OEM parts than go aftermarket and my local Lexus dealer quoted me $780 for a set of front pads and rotors and $810 for the rear for f sport stuff. Thats way too much to be spending on brakes every 15-20k miles. Any advise would be very much appreciated!
