To solve this problem BMR has come up with a solution in the form of their Tubular Chassis Brace.Tubular Steel Construction. Made in the USA from TIG welded heavy wall DOM steel tubing for superior strength and rigidity, this BMR Front Chassis Brace is completed in a durable black hammer-tone powdercoat finish for great looks and long lasting corrosion resistance.Easy, Bolt-on Installation. The BMR Suspension Tubular Chassis Brace is engineered to be a direct bolt-on upgrade using just basic hand tools. There is no drilling or welding required for a clean straight forward installation.Radiator Support Compatibility. This BMR Chassis Brace is compatible with the stock OE radiator support (on 2011-2014 models) or with BMR's Tubular Radiator Support part# RS003. 2005-2010 models must use BMR's Tubular Radiator Support part# RS003 or an OE 2011 radiator support.Application. This BMR Suspension Tubular Chassis Brace is designed to fit all 2005 to 2014 Mustangs with a BMR tubular K-member installed, including the V6, GT, Bullitt, BOSS Shelby GT500 models.
