You guys know that Coleman builds custom spindles pretty cheap, like under $500, that would allow the use of a variety of big bearing Coleman hubs (also very cheap) This would solve the camber/roll center issue on B and E bodies by having one made taller, and allow you to use a much stronger hub, all under $1500. As far as brakes, 6 piston calipers are nice if needed and the piston area has been calculated and MC and brake pedal ratio setup. You can have more brake force than the tires can use. Everything has to be designed or calculated based on the application.
