I dont know too much about aftermarket brakes for the 300C, but they look like mopar versions of the SRT brakes, so they must be pretty solid. As for the price, I'm assuming that is for either the front or back, but still seems a little cheap. I remember seeing Willwood and SSBC's for like a grand more for either front or back. But those could have also been really big brake kits, I think like 15 inch rotors. These ones are 14.2 in the front right?
