Cusco Blue Drift Knob fits all Nissan except the Nissan 350Z (which requires modification to factory E-brake: Though many customers have installed successfully on their 350Zs we cannot guarantee fitment). These JDM drift buttons are more than they appear. These replace the button on your e-brake allowing you to depress the button and the E-brake will always release when you let go of the handle. This means that instead of having to thumb the button to release the brake you are able to simply yank up and let go.
