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. We recommend adding a Wilwood proportioning valve as well.

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.
