Car preparation

Even for the standard saloon car classes, there’s still a substantial amount of work to be done to prepare a car for racing, - but it’s not rocket science, and should be well within the scope of an enthusiastic amateur with a socket set, a welder, and an angle grinder. For more details please ask Ben McKenzie

The basics are:

• Car must retain its original shape / silhouette.
• All flammable materials to be stripped out of the car
• Doors must be welded shut with three 1" welds up each upright and 1" weld at the bottom of each door. Front doors may be stripped down to the skin.
• All glass must be removed, including mirrors
• Steel weld mesh 1"x1" x 12 gauge must cover the windscreen aperture.
• Air bags / steering locks must be removed
• A safety harness to BSI standard must be fitted (3 point minimum)
• A racing seat must be used (Not a kart seat!)
• Head restraint must be fitted above the seat, inline with the back of the crash helmet.
• Fire Extinguisher of minimum 1kg foam or dry power must be within the drivers reach when harnessed.
• Prefix and numbers on the doors must be 9" high, numbers on the roof fin must be 6" high
• All wiring may be removed
• An isolation switch must be fitted to the off side scuttle.
• A brake light must be fitted to the rear of the car
• The fuel tank must be taken out and replaced by a single non-spill tank of maximum 3 gallon capacity
