NA go with 4.30 or 4.56 liveable on the HWY

FI go with 3.73 for positive displacement (roots) blowers, or 4.10's for centrifugal

i got 4.10s in my 99 today actually so far i love them the best thing i ever did so far
but my 1st gear still hits 30 so i couldve even went with 4.30s

I have 4.10 in mine. I love them, i drove out to WFC vlast summer and i got 29.8 mpg. You could live with 4.30 there is not alot of difference. I just wanted to make sure the speedo was accurate

29.8 mpg ... wow. thats better then i get with 3.27's. What kind of speed where you traveling at? the more i drive it, the more i realize that the car does love to cruise at a little more rpm, it seems happier at 90 then 65-70, with the extra rpms.

Go with 4.30s...i love mine

If you stay N/A and use the car to drag race I would not reccomend 4.10's. They require you to shift to 4th really close to the finish and that hurts your trap speed and ET. I have 4.10's and will be switching out for 4.30's as soon as I can get a spare buck.

4.30s

I wish I went with 4.56's, but the 4.30's are a great street/strip gear, he will like them.
