Kevin, don't worry about Honda, Acura or Mazda. They are toads and need all the help you can give them.
Those Volvos are bound to dominate if given anything they actually came with. That is sadly a concept with Improved Touring also. Unfortunately when these cars were introduced into IT they were for the most part competivlely engineered by one the best preparers in the business and well driven by numerous folks. The sadest thing about the whole mess is that we all race for fun and the 140 Volvo is about the most fun car to drive ever---not scary fast, but well balanced and behaved on it's tiptoes, sadly lacking aero advantage by standards of the last several decades. Maybe aero ought to figure in to the rules process a little more. There are other cars that are being cheated in the same process. ( BMW 1600,2002 anyone? )
