What's a "Little Big Brake Kit"? It's a light, stiff four-piston caliper mounted on a stock rotor. This gives you great pedal feel, a huge selection of pads that are easy to change, a drop in unsprung weight and low consumable costs.
The calipers are four piston Wilwood Powerlites. This is a newer design than the old Dynalite, offering improved stiffness and lighter weight. They form the basis of our Little Big Brake Kits for other models as well. Because the new calipers are aluminum, there is a significant unsprung weight savings: 5.45 lbs per wheel in the front when compared to the standard ND brakes. That's an overall savings of nearly 11 lbs of unsprung weight. Even the Brembo cars can save over 3 lbs per corner.
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.
As a bonus, these calipers are more compact than the stock ones. This allows the use of 15" wheels. We've tested them with both 15x8 and 15x9 Gen4 6UL wheels. They also fit under stock 17" wheels without the need for a spacer.
These calipers are hard-anodized to make the coating very durable and resistant to changes due to temperature. This hard-anodizing means that there's no dye, which means that the exact shade can vary. It's important to note that the shades of grey will likely not match perfectly. We can't accept returns due to mismatched caliper colors. If you'd like your calipers to match perfectly, please choose one of our big brake kits in red powder coat.
Fits 2.0L cars, including all North American ND MX-5s. 1.5L cars use a different rotor size, so you'd need a set of 2.0L rotors to go along with the kit.
Will they fit your wheels? Well, we know they'll fit just about any wheel we've tested and they definitely fit behind stock ones, our Kōgekis, and our Tobus. We do recommend you check against your own, however. Use our handy template to be sure.
Includes BP-20 front pads and braided front brake lines. You will reuse your stock rotors. Also available as a four wheel kit.
Note: The piston sizes are well-matched to the stock hydraulic system, an almost perfect match to factory sizes and the same 3.0 square inch setup as used on other kits. Also, the 5.0 square inch pad size is very slightly smaller than the 5.4 square inch of the factory (that's 7% smaller, not 30% as claimed elsewhere) but the swept area is the same.
