New to IT. Currently race in Porsche club and NASA with a 1982 911 but ITR doesn't look that appealing - my car doesn't look competitive and I would imagine the fields are still pretty small. Figured I try a BMW and race SCCA and BMW. Which IT class are the BMW's competitive in? Are they the class killer in any particular class? I was thinking about an e30 platform. Looking for a full field with tight racing. Thanks for the help.
