Thats about where I'm at. I could not find any quantification on how much improvement it makes.

I just put 3.73's in my car and I think it helped me out a great deal. Before I had 2.73's and I was ran a 14.5 at 92mph with a 1.8 60'. Right after the gear install I ran a 14.2 at 96mph with a 1.5 60'. That was immediatly after the install. I will run again in about 2 weeks, after I am completely used to the gears and hopefully I can run at/or around a 13.9.

i would do gears, its definitely worth it, if not for ET gain for the sake of driving around, it makes the car 100x more fun to drive, b/c u dont have to rev each gear to high RPMs to move through traffic, and its just more responsive. You dont need to go insane to make gears worth while, i went from 3.08 to 3.55 and I'd do it again in a second.
