a guy here in pcola has a rear end up for sale with a posi and 3.42 gears in it. i currently have 3.23 gears in my car with a t5 tranny. how much will my mpg city/highway suffer if i install this rear end and what will my top speed in second gear be? i would really like to know before i go out and get this rear end.

Re: question on gear ratio 3.43
doubt you'll see much of a change in gas mileage at all...you probably won't feel much of a difference at all.

Re: question on gear ratio 3.43
At sunny south? I have been over there a couple times. I was on southernfbody, didnt seem to active, i still snoop around sometimes over there. The mx6 seems like it would be more nimble on that little course.Team NoVa

Re: question on gear ratio 3.43
not really it has a hard time rotating around the cones. it has good turn in but comming out of the corner it really has trouble. if im running it im going to be on the r comps so ill be able to adjust the tire pressures a bit more then with street tires.Comment

Re: question on gear ratio 3.43
Ever tried left foot braking with that MX6? Might help with some of your issues in leaving the corners.
As for the gear change, it shouldn't be a noticeable change in gas mileage from 3.23s. Acceleration should pick up a bit though.'99 Camaro

Re: question on gear ratio 3.43
ok thanks. i never got the hang of left foot braking since i started out in a 4wd audi quattro now the mx6 and the camaro. i may try it to see what it does but i would rather set up the car so i wouldnt have to. im still working on my heal and toe since the mx6 used 2nd and 3rd gear for almost everything and im going to be using 3rd more now since i put the stock turbo back on. im going to try some toe out to see if that will help at all for the turn in.Comment
