I'm bringing this thread back a little bit but is this a good deal? Front wilwood 6 piston calipers with slotted and vented rotors for 900? I know the Cobra setups will cost up to 500 if you get the calipers from buyfordracing and the other parts from american muslce, or maybe get them used for cheaper. So, Cobra setup for 500 or the wilwood's for 900? Opinions?
