Z1 Motorsports Brake Master Cylinder Brace is the premier and most affordable brake upgrade you can buy for your 370Z or G37. It is effective for Z's & G's either on the track or in traffic.  Increase brake response and driver confidence.

When pressing the brake pedal, the force applied is transferred through the pedal assembly and unto the firewall. Although reinforced, the firewall is still easily manipulated. Z1's Brake Master Cylinder Brace provides a halt to this flex by securing the Master Cylinder against a solid aluminum bracket fastened directly to the chassis.

If you are not convinced of the need for such an accessory, grab a friend and pop the hood or your Z. Remove any covers around your brake Master Cylinder. Have your friend sit in the driver's seat and press hard on the brake pedal a few times. Watch the Master Cylinder move towards the front of the car with each press of the pedal.

Unlike similar products, Z1's Brake Master Cylinder Brace is a simple bolt-on solution (no machining required!) and eliminates ALL of the firewall flex, giving you the quickest reaction time from when you press the brake pedal to when pressure is applied to the rotors. Couple this brace with high temperature fluid, braided stainless brake lines, upgraded pads, and rotors, as found in Z1's Brake Upgrade Packages, and completely transform your braking experience.
