A minimum 4-point harness must be fitted and be of decent quality with no rips or frays to the construction (these do not need to be in date). 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 manufacturer’s recommendation (as horizontally 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.
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.
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 the driver’s as should the harness (these do not need to be in date). The rear seats must be removed completely.
ALL seats and harnesses must be securely fitted.
Recommended – 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.
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 sub-frames, the seat fixings must be attached to 125mm x 125mm spreader plates.
A minimum 6-point roll cage must be fitted including a single door bar, this can be either bolt in or of welded construction.
Roll cages must be of CDS, T45 or rollover tube only.
Recommended – The main hoop of the cage is to be constructed from 45mm x 2.5mm or 50mm x 2.0mm tube.
38mm x 2.5mm or 45mm x 2.0mm tube is permitted for all other parts of the roll cage. A 1mm tolerance in tube size is permitted.

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 main hoop can only have 4 or a maximum of 5 bends (if it has a 5th bend, it must be no more than 15 degrees).
The front A-pillar legs to have no more than 3 bends (may require bracing bar).
The windscreen bar is to have no more than 2 bends.

Apex/Cusco-style dash dodger cages are NOT permitted at all. Dash dodger refers to those cages with the S-style bend in the front cage leg to curve around a standard dash.
Single door bars are required on the driver and passenger side of the vehicle with a height of approximately 450mm from the ground.
Door bars can be removable, however, they must be secured correctly using appropriate brackets and high tensile 10mm (minimum) bolts produced to ISO 8.8 or higher.
Recommended – Double door bar (‘Nasscar Style’) or ‘X’ type bar.
Roll Cage Padding. Any part of the roll cage within 150mm of the driver’s or passenger’s helmet must be fitted with appropriate padding to provide protection in the event of an impact. We recommend this is flame-resistant padding and that any materials used to secure the padding (i.e. Cable Ties) are secured in a safe manner.
Convertible vehicles do not require a hard top to compete but the soft top must be secured in the ‘up’ position whilst on track.
Convertible vehicles require an ‘X’ or ‘V’ in the cage above the driver/passenger area.
A minimum 1ltr hand-held fire extinguisher must be fitted and within reach of the driver when sat in the seat with harnesses fitted. This should be mounted in an approved cradle or bracket. In addition to this, a minimum 2.25ltr plumbed-in fire extinguisher system must be fitted with two nozzles. One nozzle must point towards the inlet side of the engine and the other point towards the driver’s legs.

If motorsport fuel cells are fitted within the vehicle, a suitable flash firewall must be fitted between the driver and the fuel cell. Please ensure that the flash firewall has no visible gaps, these must be sealed with the appropriate material. There must be a rollover valve fitted to the fuel cell.
Recommended – Fluid Hoses. Any lines used to carry fluids through the vehicle must be one continuous length or braided with proper joiners. These hoses should be run along the passenger side of the vehicle away from any hot or moving parts and should be appropriately protected from any exposed metal edges.
For your safety, we recommend that all fluid lines are routed to the underside of the vehicle and protected accordingly. Any pipes, lines or fittings should be secured every 100mm along their length.
Bulk Head and Firewalls
Front and rear bulkheads and firewalls must have no holes into the driver’s compartment. Any hole fixes must be rubber grommets or welded patches – silver flash tape is not acceptable. (If we can see light through the bulkhead, this will be a ‘fail’.)
If the fuel filler is located within the boot area, there should be a suitable splash bowl with a drain to the outside of the vehicle or other suitable drainage holes in place. Nitrous Oxide is permitted, and bottles must be securely fastened and correctly maintained.
Electrical cut off
An FIA electrical cut-off must be fitted and within reach of the driver when sitting in the seat with harnesses fitted.
An electrical cut-off pull must be fitted to the outside of the vehicle, on the passenger side in or around the base of the window screen and clearly marked with a regulation safety sticker.

OEM screw-in type is no longer allowed.
Vehicles must have present and fully visible rear brake lights (ie; OE lights or retrofitted). ALL vehicles must have an LED brake light strip fitted at the top of the front windscreen, this should work in conjunction with the rear brake lights.
The front windscreen can be either glass or Lexan polycarbonate (with a minimum thickness of 4mm) free from any major cracks or breaks.
Driver and passenger door glass can be replaced with polycarbonate windows. Window nets can be fitted and are permitted. These should be screwed or bolted securely in place and must not inhibit driver visibility. Windows or sliding hatches can be open but by no more than two inches.
Rear screens can be replaced with polycarbonate.
We will not allow any vehicle with a fluid leak to compete. Any leaks will void the vehicle from competition until repaired and inspected by the appropriate Drift League GB or Gtec Events staff.
Catch tanks for oil or water should be visible and easily checked by inspection and Drift League GB or Gtec Events staff.
Tanks should be checked before each round of competition to ensure they will not overflow.
These must have all glass removed and be replaced with metal fixed securely in place.
Class 1 – Front tyre choice -open. Rear tyres -restricted to a minimum of 200 tread wear and a 265mm maximum tread width.
Class 2 – Front tyre choice -open. Rear tyres must be road tyres only -no slick, semi-slick or cut-slick tyres permitted. Tyres must be E marked with a 265mm maximum tread width.

This will be tested during the inspection and during the event by both Gtec staff and venue staff. THIS WILL BE 102db STRICT ENFORCED LIMIT via the venues.
Appendix A: Floorpan, Bulkhead and Transmission Tunnel Modifications
Prior to the first competition event for any highly modified or non standard unibody constructed drift car I.E FWD-RWD the vehicle MUST have completed and passed a prior arranged vehicle inspection at one of our workshops (inspection costs will apply). At the time it passes it will be issued a tech approved sticker which must be attached to the cage next to the round inspection sticker. If a vehicle’s tech sticker is withheld for any reason it is the owner/driver/team’s responsibility to meet myself (Gordon McIsaac) or head scrutineer to discuss what actions are required to meet regulation compliance. Drift League will retain a record of all cars tested pass or fail.
Bulkhead modifications are permitted BUT as minimal as possible to allow engine fitment to an absolute maximum of 1 cylinder. If the bulkhead is being modified it should only be done as a last resort after other options such as a rear radiator setup to gain the extra room required. There must then also be further strengthening added to the transmission tunnel around the gearbox bell-housing area. Transmission tunnel must be made of 1.5mm steel, or fortify the original tunnel with extra 1mm steel over-welded.
Transmission tunnel width may be no wider than 460mm.
There must be a minimum of 250mm between bottom of windscreen and top of transmission tunnel.
All modifications to floor pan, tunnel and bulkhead must be to high standards with correct and suitable materials.
All rules and regulations within this document are subject to continual review and update on an event-by-event basis. Any changes will be announced.
