I don't think you can analyze the year's results the way you're trying to do and derive any meaningful results. The Corvette's success this year is almost entirely attributable to one person: Lane Borg. Lane has yet to run against a top driver in an S2000 at a Tour this year; the S2000 wins were at events where he wasn't present.

Unfortunately, with all due respect to those who will be campaigning S2000s in two weeks, there are no known jacket-level drivers running S2000s at Nationals this year. Conversely, Lane is already a national champion and Solo Triad winner in his Corvette, and Michael Heinitz is a "national championship event winner" (or whatever they call winners of provisional classes) in his MX-5. Odds are quite good that Lane will win; odds are very good that either Lane or Michael will win. That says nothing about the S2000's competitiveness one way or another; they would both still contend for jackets even if they switched to S2000s.

 

Good point. Too bad there will be no top level S2000 drivers running this year, I would love to see a first place battle between the S2000 and the C5.
