The car is built to comply with the rules of the MSA (Governing body of UK motor sport) and the TR Register. The car runs in Class F (renamed from Class G for 2003 onwards), for fully modified cars over 3.0 litres.

The main restrictions which applied were as follows:

  2. Wheels should be no wider than 7" with a diameter of 13" and fitted with Yokohama tyres
