The original 11.750″ big brake kit!

We designed our own BBK after testing many others. We start with a 11.750″ rotor and designed our own hats. CAD designed and FEA tested, our hats weigh just over 1lb and are designed with cooling reliefs for great thermal dissipation. Our hats and brackets are CNC to a tolerance of .002 for true run out and proper alignment. Our kits are direct bolt-on, unlike cheaper kits that require hub rings and alignment shims. By doing this we are able to offer a brake kit that does not require spacers to clear most aftermarket wheels with an 11.750″ rotor.

What’s Included:

  • Wilwood Dynapro lug mount calipers – 12mm pad
  • Wilwood Dynapro radial-mount calipers – 16mm pad
  • Rotor of your choice – fixed or floating – Floating rotor installation guide
  • V8R billet 6061 caliper brackets with mounting hardware
  • DOT approved stainless steel brake lines
  • Type-III black hard coat anodized plated hats
  • High-performance brake fluid
  • Can be upgraded to a four-wheel BBK

Wheel Fitment

We wanted to offer the best performance in every single category, including wheel fitment. Our 11.75″ kits will clear most current aftermarket 15″ wheels. Check the wheel fitment templates below. Proper wheel clearance is the responsibility of the end-user.

I had no issue with this kit took about 2hours to install but thats me making sure everything is on point, watch out for your wheel sticky balance because mine hit i just bad to switch my rear wheel to front to fix the problem.


Sharp looking. Fills open style wheels with brakes and stops the car really, really well. However, the upright-to-bracket bolts (x4) are 5mm too short. I remedied that with ARP #673-1003 bolts.
