Re: FW: Jeep 4.0 in an American?

[farna@xxxxxxx]

Well, 5/16" larger diameter will still add a little braking power, but not likely enough to be worth making a new caliper bracket. Now I wonder if the rotor will fit the existing caliper bracket. There may be enough clearance there. If not, the rotor could still be turned down to fit, so it may become a part source when the Concord rotors start getting hard to find/pricey (gettting the rotor turned down won't be cheap though). One of these rotors needs to be priced! I wonder if it fits a Dakota or some other DCX product?
