Track Day - Vehicle Checklist

PLEASE READ CAREFULLY – THIS COULD AFFECT YOUR ENTRY

You are reminded that the safety of your vehicle is your responsibility at all times. The track owner and the International Jaguar E Type Register of the Jaguar Drivers Club Ltd., reserve the right to refuse entry to any vehicle, without refund, if any fault or feature is thought to compromise the safety of the vehicle, its occupants or others present at the track.

The E Type Register Track Days are arranged on an informal basis with a variety of vehicles, mostly road going, being used. However, it is important to note that circuit use exerts greater pressure for longer periods on vehicles and their components that would normally be experienced in road use. This obviously highlights the need for particular attention to safety feature and we recommend that entrants thoroughly inspect, or have their vehicles inspected, prior to use on the circuit.

We recommend that you pay particular attention to the following items and any uncertainty or wear should be discussed with a qualified vehicle engineer prior to this event.

ELECTRICAL

The battery must be secured by a suitable strap or fixing and its cap(s) be tightly fastened

The vehicle wiring should be adequately bound and clear of obstruction – particular attention should be paid to areas where it runs through the bulkhead or over metal edges where the correct grommets or packing should be used.

Conditions of wiring in highly flammable areas such as petrol tank and carburettors should be checked in particular.

Lights should be taped so that in the event of them breaking, they do not shatter on the circuit.

STEERING AND SUSPENSION

General condition of shock absorbers, track rod arms, tie bars, panhard rods, spring, etc., should be checked for any areas of corrosion or wear with particular attention paid to mounting points and fastenings. These areas will be subject to high cornering stresses at the increased speeds of circuit driving and should be in good condition.

Steering fastenings often have split pins fitted. It is important to check these and it is cheap and easy to replace worn or broken pins. They are a necessary safety feature.

Gaiters, rubbers and seals retaining grease or oil should be in good condition as leaking units may in extreme cases leave oil on the circuit. Inadequately lubricated or sealed parts will provide inefficient damping and see increased wear through circuit use.

TYRES, WHEELS AND BRAKES

Tyres should be checked for cracking around the tyre wall or between the tyre treads, for any weaknesses in the wall, or “out of round” characteristics. For circuit use, the general condition of the carcass, especially if aged, should be checked. If, for example, a vehicle is not used often, then the tyre performance at high speed is far more questionable and more likely to be affected by ageing. Standing in one particular place for a prolonged period of time can cause a flat spot or weakness in the tyre wall.

Wheels should be tightly fixed, i.e. studs and nuts checked and adequately torqued and wheel bearings checked for wear. Wheels also should be checked for cracks (especially if alloy) and/or evidence of serious kerbing which can allow tyre to deflate on high speed cornering. Wheels should be tracked and balanced to ensure safety and trueness.

Brakes should have a good feel and not pull to one side under heavy braking. Any inadequacies in their performance will be magnified at speed and can be dangerous. We will not have facilities to check these and recommend systems are checked if the driver is in any doubt. Joints should be checked for any leakage as well as checks to seals and callipers.

ENGINE AND FUEL SYSTEM

The engine should be in good order. It should not leak any oils or fluid, as this will be dangerous to all present. Gaskets and hoses should be in good order and adequately secured and fixed. If you have any doubts as to hose conditions whether it be fuel, oil or water, it is wise to change it and keep the original as your spare for road use.

Carburettors and fuel systems should have strong return springs fitted. Cables and linkages should be checked for lubrication and smooth operation.

It is advisable not to fill the fuel system to more than 70% as some vehicles do lose fuel when full on fast corners.

Noise Test Requirements

Static Noise Test – Cars maximum 105 dbs at ¾ maximum revs.

Measured 0.5 metres from the end of the exhaust pipe with the microphone of the noise meter at an angle of 45° with the exhaust axis, with the engine at ¾maximum rpm.

Drive-by Test – For all vehicles maximum 103 dbs at 10 metres from track-side.

In general it is highly recommended that all fluid levels be checked before circuit use and the vehicle must not enter the track with any loose objects inside – leave them in the paddock area.

IF YOU HAVE A FIRE EXTINGUISHER, IT MUST BE SECURED AND NOT LOOSE.

It is worth remembering that an MOT certificate should not be taken as evidence of the general mechanical condition of the vehicle.

If you are unsure of any of the points referenced, we recommend that professional advice is sought prior to the event. Your help in checking the vehicle before the Track Day is expected and appreciated. Always bear in mind, it is you who are driving the vehicle.
