Jake (mot Gulick),
First off, please re-read my post. I said that changing the gearing w/ the R&P is the cheaper and more practical way. Second, it's rules creep as it, as both Darin and Jake (Gulick) state, there is some performance advantage. Also, that's pretty much what rules creep is, you get something changed for one reason, but there's a performance benefit to be gained by changing, so you up the ante for everyone.
And, as others have argued, if it costs you $1500 for a custom R&P, maybe you picked the wrong car. I can get 4 different R&P ratios for a VW (3.67, 3.89, 3.94, 4.23) for <$400 each. These are factory VW ratios. And actually, you can get used versions of the fist three ratios for usually between $50 and $100, as they're fairly common.
George,
'facilitate moving a car between classes w/ different widths'??? Just how often do you envision moving a car between classes? If your car gets moved from ITA to ITB (7" to 6" max), sell your old wheels to a fellow ITA racer. If you're going the other way, sell your old wheels to a fellow ITB racer.
