In 2011, Ford added more rigidity to the front end of the Mustang by adding a brace between the radiator core support and the k-member. When enthusiasts replace their k-member with our aftermarket k-member, the OE brace can no longer be used. BMR has come up with a solution to this problem with their Tubular Chassis Brace.
This brace is compatible with either the factory radiator core support or BMR's lightweight Radiator Support (RS003) and is a simple bolt-in installation. NOTE: Does not work with factory K-member.
