thinking about 3.73 gears..

i hate my 373s they absolutely killed the top speed of my car and these cars have way to much of an overdrive in fifth so its like hitting a brick wall when you hit fifth

Exactly what road are you on when you maxed out 4th gear and then "hit fifth"? At 6K RPMs, 3.73 gears, 26" tall tires and a typical 4th gear ratio of 1:1, you'd be travelling at 124 MPH. Why do you need 5th? :rolleyes:
 
So I'll ask again, where are you guys doing 150 - 160 MPH (so I'll know to avoid any such towns and roads)? 150 - 160MPH on a US public highway? That's just plain stupid folks...please tell me you were on a closed course...
