That's the way to go if you can afford it. Nothing like better accelleration, better city MPG, and keeping your hwy MPG!!!!!

I used a calculator to calculate those... but with the 3.73's I know those are right, 2150 at 60 mph. 3.90s are pullin 2400rpm at 80mph, but that is w/ 94 gt... my 2800 is a little high. Somebody here said they were at 3000 rpms on the highway or something like that. Would you say around 2500 rpms or so w/ 4.10s at 65mph for a 95 gt? Still getting 3.73's, but curious.... I have 18 inch wheels also, if this makes a difference...

1) I dont know why you wouldnt be able to use 4.10's with low profile tires
2) I believe that with the new speedo gear you will still be off some but you will be close (dont quote me this stuff)
3) I wouldnt install the gears yourself. I do not have personal experience with them but I've heard that it can get very difficult w/ all the shimming etc. Its would prob be best for you to just take them to a shop the have them done for an est. $250.
