There are a lot for options for brake setups. And everyone has a different spin on what is “best”. But honestly the stock brakes on 04+ GPs are great IMHO. They are already “upgraded” from earlier model GPs. Replacing the parts with OEM is just fine. There is no magic bullet that will make your brakes much better than what they are stock without investing a lot of money. But I do have a couple tips for you. Watch out for cheap rotors, cheap usually means thin. And ceramic pads make less objectionable dust.
On second thought, I guess I didn’t answer your questions the best. I like my ceramic Hawk pads, but I can’t honestly claim they are any better than stock. My StopTech rotors are nice, perfect quality. Also, I have heard EBC green stuff pads are good.
And if your really serious and have the coin to back it up. Go for Baer brake set up front, it will only run you about 3k![]()
