Did you get the kit for 5 or 6 lug wheels? The 5 lug will have rotors off a 70's Camaro with a smaller diameter rotor than the 6 lug kit which uses parts originally for 16" wheels and a larger diameter rotor. Even though the 6 lug kit says can be used with 15" wheels it can be tight depending on the wheels like you have found out. I have a 6 lug kit and with the wheels I am going to use it will take some grinding on the calipers, a spacer and no wheel weights on the area where the caliper is near the wheel.
