I've noticed something about upgrades with these cars. I hear about getting performance chips, suspension upgrades, bars, air intake and etc... but I never hear much about calipers....I heard that the stock bmw calipers are very good on these cars, and seems to me there are much more widespread options for rotors/pads and not the calipers. Is looking into new calipers worth the time and money? or is it better just to get nice rotors and pads and spend the money on other things to upgrade?
