ROW spec final gearing question.
Once long ago (before I owned a 951) I was checking into what the final gearing of a 951 was. It came out to 2500rpm @ 75mph, or 3K @ 90. But my 89 looks like it runs closer to 2800 @ 75. I'm trying to figure out what the reason for the discrepancy is. Did the US spec cars have a higher ring/pinion ratio than the ROW spec cars?
