Our patented Boxmount big brake kits utilize a simple but effective brace on the standard lug mount caliper adapters. The Boxmount configuration offers two main advantages over a traditional single shear lug mount adapter:
- Increases stiffness to improve brake feel and reduce uneven pad wear.
- Allows a much larger gap between the bracket and spindle for our integrated 3" brake ducts

BX11
The 11" kit uses either common 11x.810 - 6 bolt rotors with our billet hats or OEM ND rotors. The ND rotors run just as cool and cost a bunch less than the 2 piece rotors. The 2 piece rotors save a bunch of weight without a thermal capacity penalty. Our optional integrated brake ducts add immensely more cooling air flow potential for track cars. Wilwood 4 piston Dynalite is standard

BX1175
The 11.75" kit uses either our custom engineered and massive 11.75x1.1 directional rotors with our billet hats. Wilwood Superlite 4 piston with equally massive 7420 pads, roughly 2.5x larger than OEM pads. Our optional integrated brake duct and shield kit add immensely more cooling air flow potential for track cars.
