Well, won't be the first time Ferrari found a "different interpretation" of the rules
I agree with you Joseff, and, if memory serves, a few examples are : steering brake system, fins to satisfy minimal dimensions, hole in the diffuser, wider tyres, engine parts substitutions in parc fermé...
BTW, I don’t think 2004 cars will be slower than 2003. In 2001 the aero modifications were lot more radical and even before the start of the season the teams regained the downforce lost because of regulations (at least that was the case for Ferrari, a man from the aero department said so in a meeting at my Uni in late ‘02). IMO the improvement of the new aero packages already overcome the lack of 1 rear wing element. Same for engines already having at least as much power as last year. Weight of cars surely isn’t increased and tyres haven’t worsened... furthermore cars are designed for shorter stints... I tend to think 2004 cars will be quite faster than last year cars. Maybe we will never see the maximum performance possible in qual trim (very low fuel load, new tyres, qual setup etc) but the pace in the race will be quite faster.
