3.90 or 4.10 in z06 I am going to be purchasing a rear end from DTE and don't know weather or not to get 3.90's or 4.10's. My friend has 3.90's in his z06 and I really like them. I don't know if I would like the 4.10's better or not. My current setup can go to 7k no problem. This is also a weekend driver. People with both please reply with likes and dislikes. My mods are in the sig.

It doesn't seem like there is a definitive answer. I guess with my heads and cam setup 4.10's would be better over the 3.90's? Which is recomended for my setup? I dyno 467 and should trap about 125-127. At 75 mph in 6th what rpm would I be at?
Thanks!

having a 3.90 rear gear in a Z06 give you roughly the same spacing/ratios as a 4.30 gear in a MN6 (f body, C5) car. I haven't run the numbers on a 4.10 gear, but i would guess it would be closer to having a 4.88 gear in a MN6 car. What RPM will your car peak at? that will be one way to help determine what ratio you will need in 4th to cross the traps at the optimal RPM.
