You werent allowed to lean on the Swiss Sierras either, for fear of denting the roof.
People wondered how Moff ran bigger rubber on the back of his coupes than anyone else. Apparently he pumped up the petrol tank untill they popped which narrowed the tank & then used a combination of the genuine inner rear guard panels swapped left front halve to right rear & vice versa, which gave him a mini tubbed rear area & didnt break the rules as no metal had been cut or added & used genuine parts.
