Looking like I'll end up with this:

3.25 Final Drive trans w/ Michelin Defender 185/70/14's.

Should drop my hwy rpm from 2960 to 2219 at 70mph. Is that considered a little under geared or just fine? Drive is for the most part literally 100% flat.

I guess if I run the numbers lets see what 4th would end up at versus the original setup. . .

.909 (LX Trans) vs .853 (CX Trans)
So 70mph on the CX trans w/ new wheels would be 2696rpm.

Now that I ran the numbers that setup is looking really good.

What number's are y'all seeing on the interstate at 70mph with the AC on *1*?
