BBI Autosport StreetCup Harness Bar (996)


Designed to Fit

  • 1999 - 2005 Porsche 911 (996 non-cabriolet models including the Carrera, Turbo, GT2, and GT3)

Product Details 

Please note, once harness bar is committed to powdercoat, it is no longer eligible for a return. We will reach out after purchase to confirm coating color if applicable.

The BBi Street Cup Porsche 996 Street Cup Harness Bar features a 2 piece design and high strength seamless tubing (1.5” x .120” main hoop & 1.5” x 0.95” rear hoops) for excellent strength to weight ratio. With our sensible approach, the 2 piece design allows the bar to be mounted to the front seat belt mounts and to the rear strut towers (stronger mounting points), and still be compatible with the factory Bose subwoofer. Other similar roll bars on the market are not compatible with the subwoofer. 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.
