For those wanting to piece together their own kits


Planning to drive hard or want more stopping power? We've got the solution. 

Don't look like a complete fool and let brake pad fade or boiling brake fluid ruin your day (or car) while you are driving hard and stopping repeatedly. We've learned that the hard and embarrassing way. This big brake kit will help keep those problems away by reducing overall brake temperatures, extending performance capabilities under high temperature demand while increasing brake pedal feel and response!

These Big Brake Kit brackets bolt up to the Rear of the 91-98 MR2 to mate a more capable Wilwood forged superlite brake caliper and significantly larger diameter 13" Rotor. These rotors will be the same diameter as the front BBK while being slightly thinner to promote proper pad temperature and brake bias.
