The upper intrusion runs along the top of the door and is close to shoulder height to give exceptional side impact safety. It can also be used as an entry & exit aid. It is positioned wide enough so the driver should not hit it with their elbows when working hard.
The lower intrusion bar along the bottom of the door splits the gap for side impact from the standard chassis up to the top side intrusion bar. Thus, protecting the pelvis area. This allows the side door to be retained and operational.
The roof diagonals add enormous torsional strength to the structure and significantly to the roof crush strength. In particular upper windscreen corner and side impacts.
Twin diagonals behind the occupants heads also give the structure the best roof crush strength and put all loads into the nodal supported chassis points.
The total cage structure helps support the original chassis from the rigors of off road competition. Like the original Canam roof frame, it completes the overall longitudinal beaming needs of the car.
The rear of the cage mounts all the way down to the rear suspension lateral link mounting plate area of the chassis. The double plating of the mounts with 4mm steel sheet reinforces the link mountings enormously. The overall longitudinal chassis stiffness is also improved. The base mounting plate incorporates a compliant tow loop.
The rear flares and iconic X3 rear tail lights are retained and unmodified.
The rear section of the cage is designed to cope with reasonable rear impact and reduce car damage enabling competition to continue.
A spare tyre can be fitted on top of the original plastic deck or, if the muffler and plastics are removed, a large up to 33” spare angled up can be fitted completely inside the rear barwork ( even with the standard air-cleaner and intercooler fitted in their original positions).
The lower rear section of the cage can be easily removed on its own to service the rear links. The rear mounting plate must be removed to perform routine maintenance on suspension components.
A rear lower cage option will be available with wider rear horizontal tube work to protect the rear corners (plastics), and keep with the vehicles style, and potentially become mudflap mounts. Removing this back section of the cage reduces the overall size of the structure for interstate shipping if required.
