Only Flyin' Miata offers four piston rear calipers with a parking brake mechanism. They use your stock parking brake cable and are a direct bolt-in.
This setup saves 3.85 lbs of unsprung weight per side.
Since they're so stiff, they don't flex when you stand on the pedal. This gives a very firm, reassuring pedal with no springiness.
The rear calipers are exclusive to Flyin' Miata, and incorporate a parking brake mechanism. The Powerlite rear caliper has been modified to use the factory handbrake cables, even using factory clips so it's a really clean install. The handbrake is not as powerful as the stock setup, so while it can be used to hold the car on a grade, it is not suitable for initiating handbrake turns. The piston sizes are chosen to match the factory ones so your brake balance is not affected.
As a bonus, these calipers are more compact than the stock ones. This allows the use of 15" wheels in the rear. We've tested them with both 15x8 and 15x9 Gen4 6UL wheels. Make sure your front brakes also clear 15" wheels! They also fit under stock 17" wheels (including BBS Club wheels) without the need for a spacer.

This kit could be used to upgrade the rear calipers on a Brembo-package car or any other ND. Fits 2.0 cars, including all North American ND MX-5s. 1.5 cars use a different rotor size, so you'd need a set of 2.0 rotors to go along with the kit.
Includes new rear stainless brake lines. You will reuse your stock rotors. Also available as a four wheel kit.
