Harness bar Streetcup roll cage. Porsche 718 / 981 Cayman BBi Autosport

Fits:
Porsche 718 Cayman

Porsche 981 Cayman

Available in Black, White, Silver, Guards Red and Racing Yellow

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 have all been carefully evaluated and addressed. With our sensible design approach, the bar mounts to the 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 is 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.

Please note that roll bars have a turnaround time of approx 2 - 3 weeks.

About Roll Cages

Porsche Roll Cages

At Design911, we supply a wide range of roll cages for Porsche models, helping you maintain, personalise and enjoy your car.

Why do Porsche Roll Cages matter?

Roll cages are a critical safety and performance upgrade for Porsche models used on track, in competition or even for fast road driving. They help protect occupants in severe accidents and can significantly increase body stiffness, which benefits handling and consistency under load. Over time, and as performance expectations rise, a properly designed cage can become an essential part of a well-prepared Porsche, supporting both driver confidence and the car’s long-term durability.

  • Keep your Porsche looking smart rather than tired or neglected
  • Help protect the surrounding area from dirt and corrosion where relevant
  • Reduce minor niggles such as looseness, rattles or mismatched parts
  • Support long-term enjoyment, pride of ownership and potential resale value

When should you review or replace your Porsche roll cages?

Checking roll cages regularly helps you spot wear, damage or age-related deterioration before it affects comfort, refinement or leads to more expensive repairs later on.

  • Existing parts are worn, cracked, scuffed, faded, corroded or missing
  • You notice looseness, vibration or an untidy appearance around the area they sit in
  • You have had related work carried out and want everything to look and feel consistent
  • You want the car to feel smarter and better cared for in daily use or before resale

If any of these apply, it is a good time to review your roll cages and replace anything that is past its best so your Porsche stays dependable and enjoyable to drive.
