If you don't have at least 400whp, don't put this in your car. The gears are very very long, and low power cars don't like that at all.

But it gets 30-35mpg on the highway

What's your time and speed at 1/4 mile? I am planning to use q45 diff for gas saving but I don't know if it will hurt my 1/4 mile time.
