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
  • 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.

Beware big brake we description

Ordered the Wilwood big brake it for my 04 Miata and although the description says includes brake fluid and no mention of not having pads Neith are included. When I contacted three I was told the website is outdated and basically oh well. Do yourself a favor and get the Goodwin or flying Miata kit. They come complete so you don’t have to spend $70 more on stuff that should be completed on a “ready to bolt on” kit like the website states.

Hi Tony - We removed the brake fluid from our kits because mixing fluids is not recommended by the manufacturer. Different fluids have different boiling points and mixing them can cause a soft pedal and possible system failures. We recommend using the same manufacturer of fluid that is already in service or a full system flush during installation. Our website is being updated to reflect this.

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.
