Driver Application to join Historic Touring Cars New Zealand

Prospective applicants can contact the Chairman of HTCNZ to determine whether the driver and car are suitable to join the class.
The driver must have adequate racing experience to safely race in the class.

The HTCNZ car eligibility committee will determine whether the car is suitable to join the class. A car inspection may be requested to determine eligibility. Car eligibility is as follows.

Vehicle Eligibility Historic touring cars New Zealand

To be eligible to race within the Historic touring car Group, the car must either be a genuine period saloon racing car that competed in a significant race series, either nationally or internationally between the years of 1970 and 2000, in the following groups, European Group 1 or 2 Saloon cars, British Touring Cars, Australian Group C, International Group A, or 2 Litre Super Tourers, NZ 2 Litre Schedule S Touring Cars, or an exact replica of a car that fitted the above criteria. Consideration may also be given to other genuine period racing cars that are outside the aforementioned criteria.

Genuine vehicle: This must be as it was raced in period. Current HTCNZ sponsor decals, and current drivers name may be added to the car.
Bodywork: Must be identical in shape, construction and material used, to those used in the vehicle in period.

Engine: Must be identical to the engine used in the vehicle in period. The engine must have the same number of camshafts, valves and cylinders as was fitted to the original competition version. The materials of the main components must be as was fitted to the original competition version. Where original parts are no longer available, substitute parts may be used, providing these provide no significant performance advantage. ECUs may be substituted for a modern unit providing that no more functions than were available in period are used. Electronic fuel injection cannot be substituted for mechanical injection, where mechanical injection was originally fitted to the vehicle.

Gearbox. Where possible the original gearbox must be used. If parts are no longer available for the original gearbox, a gearbox of a similar type and number of speeds as used in period can be substituted.

Brakes: Brakes must be the same as originally fitted. Brake disc size, calliper numbers, and number of brake calliper pistons must be as original, or as allowed as an option in the vehicle’s period Homologation papers. Master cylinder sizes can be substituted providing they are operated by the same system.

Suspension: Suspension must be as per the original vehicle. Shock absorbers may be changed if the originals are no longer available. Replacement shock absorbers can only have the same number of functions as the original shock absorbers.

Interior: Interior should be as per original. A passenger seat may be fitted. Any changes involving driver safety may be made. Dashboards and gauges should be as per original. Period style instruments may be substituted to replace non-functioning or damaged instruments.

Wheels and Tyres: Wheels and tyres should be as originally fitted in period. Where suitable tyres are no longer available for a given rim diameter, an application may be made to the acceptance committee to change the wheel size to one that allows fitment of a more readily available tyre, and is visually similar to those used in period.

Replicas:

In order for a replica to be accepted into HTCNZ it must comply with the following criteria:

The car must replicate a significant racing saloon that fits into the above criteria for genuine vehicles. It must replicate a given time in the replicated car’s history. Only one replica of a particular vehicle will be eligible to compete in HTCNZ events.

All major components must be of the same type as the original, ie, bodywork, livery, materials used, engine, gearbox, suspension and brakes, rear axle assembly. The car must be constructed to a similar standard as the original vehicle being replicated and will only be accepted after inspection by the HTCNZ acceptance Committee

DRIVING STANDARDS

HTCNZ events are strictly non-contact competitive racing. It is acknowledged that accidents can occur. However, if a driver is identified to use their car in a reckless manner which leads to an unnecessary accident, this will be treated seriously by the HTCNZ committee. This may result in the disqualification of the individual from racing in the rest of the weekend event. With serious or repeated reckless driving this may result in the cancellation of the drivers membership in the HTCNZ association.
