Every car must
display a coloured disc 10cm in diameter as follows, depicting which
class their vehicle belongs to:
Blue - Classes 1 & 2
White - Classes 3, 4 and 5
Yellow - Classes 6, & 7
Red - Class 8
In the centre of the disc should be displayed the
class number using a motorcycle number plate sized numeral. On vehicles
with full height windscreens the sticker should be centrally mounted at
the top of the screen in that area where the forward vision is already
obscured by the rear view mirror. On vehicles with a small or no
windscreen, the sticker should be mounted on a flat vertical surface
approximate to the competition number. If this results in the sticker
being mounted on a background of a similar colour to itself, then the
sticker must be mounted on a white rectangle measuring 155mm x 105mm (the size of a standard competition number).
Discs are generally supplied by the organisers, class numbers
must be supplied by the competitor.
