1990-2005 Mazda Miata Big Brake Kit

One Kit – Seven Supported Rotor Sizes

The Trans4mer Miata Big Brake Kit is designed for maximum flexibility allowing users to upsize or downsize overall rotor diameters without having to purchase new brackets, or entire brake kit.   Using Wilwood 4-piston Powerlite calipers, the Trans4mer BBK is light weight and reliable, while offering superior cooling and stopping power without upsetting overall balance.  The brackets use a set of spacers to switch between rotor sizes.  Brackets and spacers are made from high strength 7075-T6 aluminum with stainless steel threaded inserts and anodized (Type II) blue.  With multiple supported rotor sizes users can inexpensively change between different diameter rotors allowing for more flexibility with wheel fitment and across applications from autocross to endurance racing.

• 235mm – ’90-93 Miata – 8.1lbs
• 255mm – ’94-05 Miata – 10.4lbs

*Mini S and 11.75″ rotors are outside of the recommended rotor range for the Powerlite Calipers but were added per customer request.  Although this combination has been tested with no issues with performance or reliability this combination should be monitored and appropriate caution should be taken if using this large of a rotor.  See notes below for additional information.
