Which diff to go with 3:25 or 4:10

[89325iturbo]

Currently have a open 3:73 on my car now. There's a 3:25 lsd and 4:10 lsd both not far from me.
My car is a 2.7i with cam and chip. It's a second car, so a majority of the time it's going to be used in town and around town. But I'm sure occasionally on the highway.
Opinions?

Not to be a buzz kill, but I would not like either of those. Too tall and too short. I like to wind out 3rd to 90 MPH so 3.64 works best for me. If you want to go shorter, 3.91 is an option.

My ETA so far just has a chip and the 3.46 torsen I installed is a profound improvement. If you have a cam i think it would be even more fun.

But a 3:64 or 3:91 don't come up very often or close by. Not looking to pay for shipping of a diff. I initially thought 3:91 though.

I would go 4.10 if it's not going to be a long- distance cruiser.

It will be fun in town and off the lights.

If you're going to be out for long drives, the taller one would work. But not
so much fun off the line.

IXs get parted all the time. The manuals use a 3.91 lsd.

4.10 (accidentally) in my 2.7i. It's fun but 4000 rpm at 80 mph gets old.

3.73 is the best all around imo. Common as well. Find yourself an lsd unit and you're golden.

^^^yeah might have found a lead on a 3:73 lsd. So hopefully that will work out.

i have a 3.73 lsd grrat condition in my eta its to much for me. go buy that 3.25 and lets trade lol. 3.73 is gonna be the best bet with your little more power and a 6500 redline
