I have a question for the rules guru's.

My 1997 BMW 318is was classified in the January Fastrack. However, it was added to the 96-99 BMW 318ti Sport, spec line.

That spec line is fine for me except, the specified wheel diameter is 16 inches. The car came stock with 15 and an option for 16. The GCR states "Cars may not fit wheel diameters smaller than those listed on their spec line. All other cars shall retain the wheel diameter fitted as original equipment for their make, model, and type."

So which is it, stock or spec line?
