ExtReme Subframe Down Tube Braces


For race chassis strength and look, add a pair of Speed Tech Performance all new Down Tubes! These supports have been designed to increase structural rigidity of your car by linking our Speedtech sub frame to the strong structural corners of the firewall. Our Down Tube Braces are constructed from 1.5″, .120 wall DOM tubing that is CNC bent for consistent fitment. Computer designed and machined Lock Down tube ends allow easy unbolting for engine bay servicing. Down Tubes come in a raw steel finish and tubing ends are left unwelded to allow for a custom fit in every vehicle. Stainless steel mounting hardware is included for just the right finish. Parts vary just slightly between Pro Touring and ExtReme subframes, order correct part for application below.
