Boxmount big brake & duct kits @ Supermiata

[949 Racing]

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

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 (https://949racing.com/product/boxmount-brake-duct-kit-for-bx11-bx1175/) add immensely more cooling air flow potential for track cars. Wilwood 4 piston Dynalite is standard

BX1175 (https://949racing.com/product/supermiata-boxmount-11-75-front-big-brake-kit-90-05-mx5/)
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 (https://949racing.com/product/boxmount-brake-duct-kit-for-bx11-bx1175/) add immensely more cooling air flow potential for track cars.

If you aren't sure which pad compound, check out the chart on the product page. Give us a call or email if you still aren't sure. A surprising number of BX11/ ND (11") rotor kits go out with G-Loc GS-1's their street pad. Silent, low dust and a bit higher performance than OEM. That basic combo works great on a daily driver when paired with GS-1's on the otherwise stock rear brakes. Perfect balance, modulation and shaves about 7lbs off the front. I run GS-1's on my 30AE.
