Rear Gears and RPM

961 Views 3 Replies 3 Participants Last post by  flybyu
I purchased my Vette used and think the car has stock 3.42 rear gears set on
my M6 car. On the hwy running at 120km/75mph in 5th gear I am at 2400rpm
and in 6th gear at 120km/75mph the car is reving at 1600rpm.

Does anyone know what the rpm for 5th and 5th would be with a 3.73, 3.90 or 4.10 gear set?

I was interested in what the rpm increase on each set would be (200,300?)
and what rpm would be good for hwy cruising?
