From a selfish point of view, I'd be keen to see an open classics class in there somewhere, ideally with a sub 55mm max rear track width to avoid the Porsche 914 dominance and allow the likes of Escorts, Alfa Giulia's, Fulvia's, Triumph's, Healey's and Mini's (if you're very brave) to compete

I thought actually we already have the Classic Classes of that type in the " American Road Race" and in the "Endurance & InterSeries" which excludes the Porsche 914/6 based on the era's, so to make this Proxy different and to ensure that the Porsche 914/6 has real competition I judged that putting all the similar "Pro cars" together in one class would be more appropriate this time around. As a matter of interest my SRC Porsche 914/6 has a rear wheel width of 54.6mm, so still qualifies for a Classic 55mm rear track Class as it does under the current "Classic Class Slot Rally UK" rules. I could probably even make it fit Kevan's 54mm width Classic Rally Class by changing the rear wheels or tyres  

One thing I could do of course is just to exclude the SRC Porsche 914/6, or NSR cars etc from competing (as some proxy's in fact are doing) but  I prefer to be inclusive but try to make them fit into a class which makes the outcome far from certain, as in the current American Road Race "Modern Trans Am & NASCARS Class D"
