[BYEBYE2U]

You def want 4.10s in an auto no doubt. You will be very happy with them. I might be going 4.30s, if not then I will be going 4.10s.

4.10's are the ****, dont fear the gear.

i think 4.30's are a little overkill though.

3.73 or 4.10's. You wont find one person who complains about their 4.10's if that helps at all. You'll find a big difference in acceleration. They acually are a really good mod for the price. even after a labor charge. its still well worth it. Id say go for it if you have the money. i think its around 500 total with labor. not too bad. Maybe less. The gas milage may hurt you though. i think 45mph is around 2,000 RPM or something liek that in 5th gear maybe. Not positive. maybe even 1700. not really sure. im sure someone else on here will know

i think 4.30's are a little overkill though.

The reason I want 4.30s is because I'm building for a TT setup. But since I have twins due in a few months, this is a looooong term goal. So for now I might go 4.30s 'cause even if I do get say 315 rwhp, the track I live by is at 6000 ft which translates to about 258 rwhp which I think is good for 4.30s. Then, many years from now, I will change my gears to 3.73s or 3.55s when I get the TT setup.
