Wheel clearance is one of those details that rarely gets attention until it becomes a problem. The brake kit can be correct for the vehicle, everything installs as intended, and then the wheel goes back on and contacts the caliper. At that point, progress stops and frustration starts.
This is especially common with disc brake conversions on classic vehicles. Drum brakes were compact and hid everything inside the wheel drum. Disc brakes place the rotor and caliper closer to the inside of the wheel, which changes how much space is available. CPP disc brake conversion kits are engineered to work within factory suspension geometry, but wheel clearance still depends on the wheel itself.
The good news is that wheel clearance can be measured ahead of time. With a straight edge and a tape measure, it is possible to understand what will fit and what will not before final assembly.
This process applies across CPP supported platforms, including Chevy C10 trucks, Chevelles, Camaros, and other classic GM, Ford, and Mopar vehicles.
