5.6.2 Prohibited Modifications:

5. Ground Clearance – Lowering the car so that the bottom of the Z section of the chassis (the
lowest point of the chassis on Aero 8), measured at a point midway between the front and rear
wheel centres (at the toeboard on traditional models) is less than:
Classes A, A 4 cylinder, B 4 cylinder, E(1-7) - 102mm.
Classes A Aero 8,NPlus8, B Aero 8(incl GTN) - 127mm,
Classes B 6 cylinder & 8 cylinder, C, D, E, F, R - 130mm.
Class E(8):- 140mm


Gambalunga,
The 'Z' sections are the two main steel chassis rails either side of the car. At no point ie. at any point through the length of the car, should they fall below this level of clearance.
