Design

The BBi Street Cup Harness bar features a 2 piece design and 4130 chrome-moly steel tubing (1.625” x 0.095) for excellent strength to weight ratio. With our sensible design approach, the 2 piece design mounts to frame structure, utilizing factory bolts, to provide the 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.

Inspired by Porsche’s motorsport program, the BBi Street Cup product line represents the culmination of our winning experience in professional motorsports and the extensive R&D efforts with our in-house fabrication, suspension engineering, and engine development programs. All of the experience gained with our successful racing background combined with state-of-the-art materials and the highest quality manufacturing have yielded performance upgrades that are worthy of the Porsche 911 name.
