Harnesses must be attached securely to the vehicle’s body or roll cage (not to the seat frame) for both the driver and the passenger. Shoulder straps should be mounted as per the manufacturers recommendation (as horizontal as possible but not exceeding 45° angle).
Recommended- 75mm straps with safety belt eyes installed with a 50mm x 50mm spreader plate underneath the vehicle to stop any fixings pulling through the floor under hard impact, unless original belt mounting points are used.
The shoulder harness should be secured directly behind the seats.
ALL seats and harnesses must be securely fitted.
Driver and passenger seats must be bucket style and must not be damaged (these do not need to be in date). There must be NO excessive play in the runners or fixings.
Competing vehicles to have an FIA approved racing seat for the driver and passenger. This does not need to be ‘in date’ but must be in good condition with no stress damage or cracks.
The passenger seat may be removed altogether. At some venues, it MAY be possible to carry passengers. If so, the passenger seat must be to the same standard as driver’s as should the harness (these do not need to be in date). Rear seats must be removed completely.
Seats must be fixed with a minimum of four 8mm high tensile bolts constructed to ISO 8.8 or above. If not using the factory mounting points on aftermarket subframes, the seat fixings must be attached to 125mm x 125mm spreader plates.

All joints to be welded or be secured by a 2-bolt fixing using high tensile fasteners produced to ISO 8.8 or higher.
Cages are to be bolted or welded to the vehicle body using plates that are a minimum of 3mm thickness and are no smaller than 125mm x 125mm square. If the cage is a bolt in type there should be an additional plate on the underside of the vehicle secured with 3 bolts for the main hoop and two bolts for all other fixing points – all bolts should be high tensile, built to ISO 8.8 or better and be a minimum 8mm diameter.
The main hoop has to be no further back than 150mm from the driver’s head.

The front A pillar legs have no more than 3 bends (may require bracing bar).
Windscreen bar to have no more than 2 bends.
All bends must be smooth with no evidence of crimping or wall failure.
There must be a continuous 360 degree weld around each joint on the entire cage, and fusion must exist between weld and base metals.
At least one diagonal bar must be used in the rear of the cage construction (either in the main hoop or across the rear diagonals) – this bar must be straight in its construction. The upper end of the diagonal bar must join the main hoop no further than 100mm from a rear diagonal and should connect to the opposite diagonal no further than 100mm away from the rear mounting point.

The prop loop must be securely mounted as close to the center point as possible between the front and rear universal joints/rubber couplings of the first propshaft.
The prop loop must be constructed from one of the following materials:
Steel flat bar: Minimum dimensions of 5mm thickness by 40mm width.
