Detroit Speed Subframe Connectors (70-81 Firebird)Find parts that fit my vehicle

Our uniquely designed Detroit Speed weld-in subframe connectors increase your car's stiffness by connecting the front subframe to the rear frame rails. Our subframe connectors are fabricated from 2" x 3" x 0.120" wall rectangular steel tubing. Laser cut brackets are included that attach the rear of the subframe to the connector for an easy, strong, and simple welded joint. Unlike others, the Detroit Speed subframe connectors are barely visible from underneath the car. The rear of the connector is tapered to attach to the rear frame rails and also has a laser cut slot that conforms to the rear seat floor pan. The connectors are bent and TIG welded in a fixture for accuracy and repeatability. Our subframe connectors do not interfere with seat attachment hardware or the installation and removal of the rear leaf spring pocket. Can be installed on convertibles. Additionally, the molded factory carpet will still fit over the subframe connectors. Our weld-in connectors are supplied with templates, pictures, and detailed instructions for installation.
