Flyin' Miata NA/NB rear brake upgrade (stock calipers)

As anyone who's serious about braking knows, proper proportioning is critical to the shortest possible braking distances. It's why we strongly recommend four wheel upgrades instead of just big brakes in the front.

If you have upgraded your front brakes but not the rear by installing a front-only big brake kit, you will find that your car has unbalanced braking, leading to longer stopping distances. This rear wheel upgrade will deal with that by adding slotted 11" rotors in the rear along with Porterfield R4S pads (a good match to the Wilwood BP-10 used in the standard Wilwood kit), stainless rear lines and our adjustable proportioning valve kit. A nice side effect will be a more visually balanced car.

This is the back half of our Stage 3 Big Brake Kit.

We don't recommend putting this setup on your car without a front brake upgrade of some sort. Not required for the FM Little Big Brake Kit, although it's a good match if you also increased your rotor size to 11". Your factory rear calipers are retained so you have full parking brake function. This setup will fit under every 15" wheel we've come across.
