"Open the hood on your 350Z and have someone step on the brakes. You'll see the master cylinder dive towards the frame. This hurts your braking performance & softens up the brake pedal. Our Master Cylinder Brace supports the cylinder and translates that wasted motion into braking force. You'll notice the improvement immediately. This brace consists of a adjustable red anodized billet aluminum piece with a delrin support cup and CAD plated mounting bracket and hardware. "
