Thank you. You have rated this product.

Upgrade your rear brakes to lightweight and rigid 4-Piston calipers, AND keep your parking brake! Great match to the Brembo front brakes or any of our own front caliper upgrades or big brake kits. Fits right over your factory rotors, no need to change rotors to run this kit (photo shows installed with our rear Superlight wave rotors, available separately on this site).

RIGID and ultra light 4-piston caliper for improved braking response over the standard single piston OEM brake calipers, reduced unsprung mass, wider pad selection, better looks and MORE FUN.

Comprehensive kit includes:
* Powerlite 4 piston calipers with parking brake
* CNC Aluminum Mounting Brackets
* Stainless Steel brake lines
* All mounting hardware
* BP20 Street Performance Brake pads
* Wilwood high-temp brake fluid

Weight
This caliper kit is 4 lbs lighter per side than the factory caliper. Combine this kit with our scalloped 2-piece drop-in replacement rotors shown in the photo above and save over 12 lbs of unsprung weight in the rear!

BRIAN'S APPLICATION NOTES: I love the combo of our front and rear caliper conversions, braking much improved, looks are improved, even ride quality is much better because unsprung weight is reduced a lot. But there is one compromise in using this style of caliper in the rear, the parking brake function is not near as effective as stock parking brake. I learned to always curb the wheels when I first learned to drive but that becomes double important here because the parking brake is not as effective as stock parking brake. So, the other way to go is some folks do front and rear light two-piece rotors, front caliper conversion, and use our RED caliper paint to make the rear stock caliper RED so it better matches the front new calipers while still keeping full stock parking brake function.

Dust Boots
We occasionally get a call from someone asking if these calipers have dust boot seals because the factory calipers have them and so they assume this is a feature they need to be concerned about. Wilwood brake calipers, just like all racing brake calipers, do not use dust boots to seal the caliper pistons. This is intentional and done for several reasons, including the point that rubber dust boots can catch fire under extreme brake heat. The pistons fit tightly into the caliper so they seal without the need for rubber seals. In our decades of experience with thousands of Wilwood calipers this design has proven itself completely reliable. These calipers are suitable for road use in all climates and conditions as well as on the race track.

REVIEWS

After reading many other positive reviews on both the GWR and Miata forums I finally decided to buy this product. My main concern for many months was whether or not I was up to the task of installing the header. But with the excellent instructions on Brian's forum as well as several Miata forum threads it turned out easier than I expected. After receiving notice that the header would arrive on a Friday afternoon, I began the disassembly process. After about 3 hours I had the stock manifold out. Later that afternoon the new catted header arrived right on schedule. And it is a thing of beauty. I opted for the stainless version. Installation on Saturday morning took another 3 hours, although I could have shaved some time off of that but I was actually enjoying the process of double checking torque values and cleaning up my engine compartment. I already have the GWR catted midpipe, so that connection was a snap. I put everything back together, reconnected my battery, and went for a drive. NO CODES! Nice throaty sound with my RSII muffler, and a significant boost in power and low/mid torque. Another happy camper here. I since have added a M-E tune and I feel I have realized all of the gains that Brian has achieved on his 2012 project Miata. I've put several hundred miles on my Miata since the install with zero problems. This is the car that Mazda should have built all along. Thanks Brian.
