I'm looking for the member who owns a white C4 with a black stripe (GS Style) down the middle.
I think he lives in Illinois.
Anyway, he wrote a gear ratio calculation program that let you pick your transmission (from a list of known trannys), and then perform calculations based on rear gear/rpm/mph.
I had it on my old computer, but it died, and I would like to get another copy.
If he is still on this board, and could provide a link to download it, I would appreciate it.
