another brake question.
My 2002 x5 has 30,000 and on a few days the lights will come on for the brakes, today the stealer told me that it will be $1,076 to change all four(front and rear rotor + pads).

ok my question is can i get better brakes and pads for that amount of money ?

how about the brembo rotors?

I care about performance, so i just want to get some brakes that will perform better than the OEM rotors and pads. and still keep the cost below $1,200

how about some of these rotors ?


how about these cross drilled rotors?
