ND Stage 4 Big Brake Kit

A good match to a track-driven turbo Miata, this kit gives you big two-piece front rotors and nice stiff 4-piston Dynapro front calipers. It's a slightly scaled down version of our Stage 5 kit with a lighter weight. These are the brakes we used on our turbo ND when it ran for 15 hours at Laguna Seca over two days. Road & Track reported "...in my testing at Laguna Seca, these brakes proved measurably superior to the factory Brembo option, particularly in terms of pad-wear consistency."

Automobile Magazine simply called the brakes "breathtaking".

Stage 3 addresses the front only, as that's where the majority of the work is done in the braking system. Stage 4 adds our exclusive four piston rear setup that gives a firmer pedal, sheds more weight and provides maximum performance. 

The pedal feel and balance is excellent due to the stiff Dynapro calipers with properly sized pistons. Slotted two-piece 12.19" rotors use superior Spec-37 iron. This metal gives very long life as well as dimensional stability under rapid temperature changes. We include our own one-piece lines to avoid multiple adapters. Includes everything needed for installation. Due to these upgrades, this kit is only available from Flyin' Miata.

Powerlite 4-piston rear calipers (red)

BP-10 pads and FM steel braided steel brake lines for all four corners

All hardware required for installation - even a hose to bleed the brakes

Note that it does not include rear rotors

The included BP-10 pads are great for street use and autocross use, you'll probably want more aggressive pads such as our BP-20 or BP-40 for track use. We're unable to remove pads from the kit. 

Will they fit your wheels? These brakes (front and rear) will fit under stock 17" wheels (including the BBS Club wheels) without the need for a wheel spacer. They'll also fit under our Kogeki and Tobu wheels with no spacers. We have not yet tested them with factory 16" wheels. We do recommend you check against your own, however. Use our handy templates to be sure:

Add the bridge bolt kit to make these stiff calipers even stiffer. 

Note that brake fluid isn't included and is required. It's optional from us for shipping reasons and in case you have your own, but our options are among the best fluid you can get. If you choose that option above you'll get two 500 ml bottles. 

To make the bleeding process as easy as possible, add Speed Bleeders. Note that the Wilwood calipers have four bleeders per caliper, only the top two (per caliper) need to be replaced with Speed Bleeders.
