PART NUMBER: 61-2903
The first two generations of Mazda Miata came with three different brake sizes, depending on year and model. The largest of those options was a 10.9" rear rotor size which came on the 2001-2002 Sport Package and that size then became standard issue on all 2003-2005 Miatas. A common upgrade for earlier cars with the smaller brakes is to update to the larger "Sport Package" brakes, which usually requires new rotors and calipers. But that comes with a drawback; less pad selection for the Sport brake calipers, and in some cases, more rear brake bias than one might want.
These brackets make it possible to fit your existing 1.6L or 1.8L calipers over the large 10.9" Sport Package rotor. You keep your you keep your current brake calipers and brake pads.
You get the benefits of the larger rotor (more heat capacity and braking torque) while also keeping the wide range of pad selection that comes with the non-sport calipers. In testing we have found that with 11.75" front big brake kits that use a Wilwood caliper, the most ideal rear brake configuration for the best braking balance is a Sport size rear rotor with a standard non-sport 1.8L (94-02) rear caliper, mounted over these larger rear rotors with our brackets.
If you also need the sport size rear rotors, we offer a kit including these brackets and StopTech slotted rear rotors in the Brake Kits section of our website. We also offer several options for sport size rear rotors in the Rotors section of our site.
