PART NUMBER: 61-2189
NEW 11" Big Brake Kit by Stoptech for the 94-05 Miata. This kit has calipers with piston sizes specifically chosen to balance with the Miata's 1.8L SPORT rear brake size. If you have non-sport brakes, pair this kit with our Stoptech/Centric 1.8L Sport rear brake kit for maximum performance.
Kit include necessary brackets, hardware and brake lines to complete installation.
*** The front calipers in this kit use the DR22 pad shape. Type "DR22" into the search box on the upper left of our site to see all our pad options for this caliper.***
Caliper - Forged/Anodized ST42 with 36/38mm pistons
StopTech 2-piece calipers have the lowest amount of flex and deflection among 25 of the leading caliper models (including some monoblocks) from well-known manufacturers. This is accomplished using the StopTech patented bolt-in bridge, which is strong enough to stop distortion without sacrificing cooling through the top of the caliper.
Rotors - 11" Slotted 2-piece Floating Rotors
StopTech Pillar Vane Brake Rotors are engineered to provide superior strength while reducing rotor weight and running cooler. The diamond shaped pillars provide brake pad surface stability as well as reduced rotating weight over rotors of similar strength. Airflow is also improved over straight vane rotors, allowing quick heat dissipation that results in greatly reduced fade.
Floating Rotors: High grip cars have the ability to generate enough lateral grip to flex the knuckle or upright. As the upright flexes, the rotor pushes the piston back into the caliper. The next time the brakes are applied, extra pedal travel is needed to compensate for the piston, "knockback". The floating rotor will "take up" some of that knockback, reducing the effect. This kit is first and foremost a track-focused high performance BBK, and in our testing the floating rotor is a crucial part of this brake system. HOWEVER, please note that floating rotors can produce some "clicking" and other noises during street use.
Installation note: The floating rotors ship pre-assembled. When you rotors from the packaging, you will notice the rotor appears to be loose and can move independently from the mounting hat. The hardware is not loose, this is normal. Do not attempt to over-tighten the hardware that fastens the hat to the rotor.
Kit ships with Stoptech 309 compound pads. These are a "triple duty" performance street pad and can be used for street, autocross and LIGHT track duty. Pairs well with a street pad in the rear such as the Porterfield R4S. Race pads can be substituted upon request.
Stoptech's BBK with floating rotors was used on the HyperMiata to set the production car lap record at Chuckwalla Valley Raceway!
