I was also surprised to find the gear ratio so low. Yea, it's good for 0-60 times but it's kinda annoying at highway speeds. And I expect that it will be way too low for the turbo kit that I'm getting. I'm thinking that the most cost effective solution will be to go to a taller tire. My '95 comes with 235/40's on the rear. If I replace them with 45 series then it will be the same as using a 2.80 diff. instead of 3.15.
Of course I'll need to figure out how to correct the speedometer..
