How tall a rear tyre will you be using?
What is the ratio of top gear on your auto?
Current diff ratio?
There are calculators out there that will tell you everything you need to know.
They'll even show you how a 1" rise in tyre diametre can alter hwy cruising speeds.
It's a science and the old "hey mate, that's the wrong bloody gearing" just don't cut it anymore.
