Actually you are geared lower. Higher Ratio #'s = lower gears. Pinion gear gets smaller on numerically higher gear sets

In 7th gear i'm at around 3k rpm's at 80mph.

I'm glad I re-read this post, as I was looking into 3.9's for my auto as 4.08's would be too deep for me. After recalculating, there is only 4% difference between the 3.692 & the 3.9's. For the added cost I'm going to go with the 3.692's as they will already be in the low mileage diff I just bought Thanks for saving me a grip of cash

Does anyone have a clear understanding on how the cruise control works in the 370z? Where is it sensing it's reading from? Also is there any speedo/ Odo correction available/ needed?

Thanks again
