Yes, the difference between the Granada and K/H brake is only about 3% swept area.
One of my chief problems with the Granada brake is the hubs are so large virtually no stock 65-73 wheel will fit, adding hundreds of dollars of cost to conversion even if one uses junkyard wheels. Do the hubs of the Cobra brake fit, say, stock 65 14x5 wheels?
There are two options if installing Granada front discs; purchase wheels that will fit over the snout of the rotor, or have the snout turned down to fit the center hole of an early stock wheel.
In the case of the Cobra front rotor setup, the front hub is an early Mustang hub. Any 5-lug drum brake hub from a '65-'73 Mustang, Cougar, Maverick, Comet, etc., will work to mount the 13" rotor to. This setup will require at least a 17" diameter wheel to clear the caliper/rotor, but somone looking to make this big of an increase in braking power isn't worried about ditching the small, stock 14" or 15" wheels for larger ones.
