What advantage is there in having a radial mount caliper over a lug mount caliper?
Radial mount calipers and brackets offer a much more rigid mounting system than a lug mount design. The radial design also accommodates rotor diameter changes with a simple spacer rather than a whole new bracket. A customer with a 13″ rotor kit that wants to upgrade to a 14″ rotor would only require longer studs and spacers rather than a complete new taller bracket.
