We've been developing these for a couple of months now, and our first batch just arrived! Our billet aluminum transmission tunnel braces come in at only 9.4oz, but are significantly stiffer than the OEM brace, which is flimsy stamped steel and easily twists & flexes. Our braces are available in four different color options, and include new hardware to replace the rotting OEM bolts. They're quick and easy to install, and provide an instant improvement in chassis rigidity, especially for cars seeing track time.
