I have a 2002 Z and is a 6sp car. I want to upgrade my rear gears. Stock 3:42s i can cruise at 90mph in 6th gear at 2K rpms.
what will my rpms be at with 3:73s in 6th at 90 mph?
what will my rpms be at with 4:10s in 6th at 90 mph?

when i had the stock 3.42's in my m6 SS 90 mph was around 2,000 now with 4.10's i'm around 2,000 at 80 mph but it only lost 1 or 2 mpg on the highway and picked up a little mpg in the city.
