I'm looking at upgrading my 69 chargers 11" drums to baer discs. I've got a factory parking brake and id like to keep a parking brake in the car. I want to get a set of Cragers keystone classics in 15" but their 11" rear brake doesn't have a parking brake their 12" brakes do but it says its only compatible with 16" or bigger rims. has anyone run the 12" kit with 15" rims? I don't want big rims on my charger I wouldn't mind wildwoods but they are more expensive.
