Neither "performance difference" nor the ability to change the track with wheel spacers allows the different axle. Same is the same.

For those of you who think you might want to take advantage of the revised VIN rule, PLEASE make sure you don't live up to the naysayers' expectations of using it to make illegal cars. We fought for a long time to get this done (I wrote my first of two letters in December '06) for someone to dink it up.

Ultimately it IS about enforcement so you can run any damned illegal thing you want until one of your competitors squawks, but please help us keep this from becoming an issue even before it's approved by the Board.
