About This Product
The BBI StreetCup Harness Bar for the 981 GT4 addresses the critical details that matter for track use — harness angle, seat travel, and engine compartment access were all carefully evaluated. The bar mounts to the cabin frame structure and rear strut towers for maximum strength, using high-strength 4130 chrome moly steel tubing throughout.
Every joint is meticulously TIG welded by hand. CNC-turned inner diameter tube clamps eliminate traditional slip-fit hardware for a clean, precise installation. The result is a harness bar that is both functional and visually integrated with the interior.
Lead time. Harness bars have a turnaround time of approximately one week.
