Trackspeed Engineering 11.75" Big Brake Kit -DynaPro/Directional Vane

  • Sale
  • Regular price $969.00

-DynaPro 4 piston caliper, slightly stiffer than Dynalite for better pedal feel and more even pad wear, and uses a re-usable "W Clip" to retain the pads for a slight bump towards lower consumable costs. Pad shape 7812.

-UPGRADED Directional vane rotor. Better cooling, longer pad/rotor life.


Trackspeed's 11.75" Gen2 BBK retains the legendary performance of our original Gen1 11.75" BBK while adding additional wheel clearance. Our all-new proprietary 6061-T6 aluminum hat is Miata-specific, which allows us to place the rotor ideally within the space provided to maximize wheel clearance. Our hats continue to be the only option that allows for the use of safety wired rotor hat hardware. Our Gen2 brackets are tweaked slightly to ensure compatibility with Keisler aftermarket drop spindles as well. The world-class pedal feel and inexpensive running costs are unchanged from our Gen1 kit. 

Pair our 11.75" BBK with a factory Sport 10.9" rear rotor and 1.8L (with adapter bracket) or Sport rear calipers. Add a Trackspeed proportioning valve kit (with proprietary ultra-robust steel adapter fittings) to give your Mazda Miata incredible braking performance in any situation. 

Our recently-announced "Mega Brake Kit" Superlite option is the largest big brake kit available for the 90-05 Miata today. It is designed primarily for forced induction road-race applications which require a substantial increase in stopping power and pad longevity over what a standard Dynalite/Dynapro caliper can offer. 

To allow our customers to run the pads of their choice, our kit ships without brake pads. We can provide Hawk or G-LOC pads in street and track compounds, email for pad recommendations.
