I think if you learned to drive a stick properly, you shouldn't need to change those gears...
Swap it to an auto....
Seriously.... I have nothing intelligent to say on this topic.

Just an FYI, I've been to 172mph in 4th with the factory gearing and a 27.4 inch tire at 6800rpms. Calculator won't show that, but factor in inflation. Glad you're not tuning my car.

I am not really sure on this, but last I remember reading, no one makes gears for the Z06 diff, which I think is the same as a GS manual diff. I would give RPM a call and see what is available, if anything, before killing yourself on this decision. They are very helpful guys.

Hey Mark... don't pay attention to these guys comments. I think its the mustang in your name that's making them nasty.
