GKTech Nissan 240sx/Skyline Brake Booster Delete adaptor kit

The GKTech Brake Booster Delete Adaptor Kit allows you to convert your S-chassis or RWD Skyline to a manual brake setup by eliminating the bulky factory brake booster. Commonly used in race cars, engine-swapped builds, or tight engine bays where space and pedal feel are priorities, this kit mounts a Wilwood-style master cylinder directly to the firewall using a precision CNC-machined adaptor.

The result is sharper pedal feedback, simplified engine bay routing, and more space for custom intake manifolds or turbo setups. Whether you're going full race car or just want more consistent brake modulation, this kit has you covered.
