Goodwin Racing ND Ultralight Rear 4 Piston Caliper Upgrade

DESCRIPTION

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.

*** The rear calipers in this kit use the 7912 pad shape. Type "7912" into the search box on the upper left of our site to see all our pad options for this caliper.***

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!

This rear caliper conversion is considered a RACE upgrade for those seeking lightest weight, fast pad changes, and other performance benefits. However, the trade off is you give up most of the parking brake function. This caliper does have a parking brake, but it is severely limited in its clamping ability. While many performance minded individuals do use this rear caliper kit on their road cars, we recommend against it if you actually need to use your parking brake from time to time, or if you live in an area that requires periodic inspections of the car for registration which may include checking parking brake function.

BRIAN'S APPLICATION NOTES: I love the combo of our front and rear caliper conversions, braking from speed is 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. Note that something that helps a ton on giving more stock like grab of the parking brake is adjust the 10mm bolt at the factory handbrake handle all the way down.

We have not tried this with 2023 Kinematic Posture Control.
