Thanks for any coming answers.

 

depends on how you launch it, but it's quick none the less..
sorry to be less specific lol.

I had mine installed a few weeks ago, along with new tires and I finally got how to launch it just right.

I 'thought' about getting 3.73s, but I am glad I got the 4.10s. Feels nearly identical to stock until you get on it. Top end was NOT effected surprisingly, tops out the car real quick!

 

I feel I can only answer the top speed question: For the most part, no change. You're engine will rev higher at your top speed but our Stangs are top end-limited by drag, not gears. With my 3.55's, I'm turning just shy of 4000 RPM at 130 MPH. It's also a function of tire diameter. In short, as far as gears go, don't sweat top end.
