These are full billet brake caliper adapters for running a lightweight single plane Wilwood Brake Kit on your Nissan Z chassis.
The front adapters are designed to fit a 350Z bolt pattern on the knuckle side and adapt to a Wilwood DynaPro6 piston Caliper on .38" wide lightweight rotors. Parts Shop Max angle kits utilize the 350Z hub and caliper bolt pattern for 350Z, 370Z, and the 2023 Z.
The rear caliper brackets are offered in two options. Stock location or under the knuckle if you are utilizing a stock knuckle. The stock location will adapt a Wilwood DynaPro4 piston Caliper on .38" wide lightweight rotors to the factory location or to an aftermarket knuckle or bracket that adds a factory-style caliper for a handbrake. We utilize two pairs of these on the back of our Formula Drift Z with Part Shop Max rear drop knuckles.
The stock knuckle handbrake bracket mounts the second caliper under the knuckle to the factory emergency brake cable mount. This mount is best for those utilizing a stock rear knuckle but want to add a secondary caliper to a lightweight brake setup.
