BBi Autosport is proud to present our new highly anticipated 981 GT4 StreetCup Harness Bar. Issues such as harness angle, seat travel, and engine compartment access were all carefully evaluated & addressed. With our sensible design approach, the bar mounts to frame structure in the cabin and rear strut towers to provide the strongest mounting points and maximum protection. For superior strength and rigidity, high strength 4130 chrome moly steel tubing was used throughout and all joints are meticulously TIG welded by hand. Bolt-in installation is accomplished by using Inner Diameter Tube Clamps that are CNC turned and milled for a precise fit. These unique joints allow us to eliminate the more traditional slip fit tubes with an unsightly through-bolt and nut. The final result is a bar that is clean & functional.
