BBi Rollbar for the 991 GT Platform



Please note, once harness bar is committed to powder coat, it is no longer eligible for a return.

The BBI Street Cup harness bar features a 2 piece design and high-strength seamless tubing (1.75” x 0.095, 1.5” x 0.083) for excellent strength-to-weight ratio. With our sensible design approach, the 2 piece design mounts to frame structure, utilizing factory bolts, to provide strongest mounting points and maximum protection. For superior strength and rigidity, the bar utilizes “X” braces on both front and rear sections and each joint has been 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 BBI StreetCup program is the interlacing of technology, motorsport fundamentals and street performance sensibility. Through extensive R&D efforts of our in-house engine development program, chassis engineering and advanced fabrication BBi Autosport creates products that deliver without compromise on performance, safety and longevity. Powered by our passion, we are in relentless pursuit to elevate and enhance the driving experience through innovation, artistry and craft.
