Which gear? 3.73 or 4.10's?
Fixing to upgrade the gear in my GT and wondered if anyone had any opinions as to get 3.73's or 4.10's. Im running the 5-spd automatic in my car. Should I use a tune to adjust the shifts or leave it the way it is. Any opiniojns would be appreciated. Also thinking about putting like a 2800 stall speed torque converter in.

Most will tell you 4.10's but I would imagine it depends on what kind of driving you do most days.
I'm personally leaning towards 3.73's to get a kick in the pants without too much RPM gains or loss of traction in general driving.

Just for comparison, here is the rpm difference between stock 3.31s, 3.73s and 4.10s at 70mph (assuming stock tires and an auto trans in OD).
3.31: 2,150 rpm
3.73: 2,422 rpm
4.10: 2,662 rpm
I've ran 4.10s in mine for more than 13,000 miles (both N/A and with a blower), and I have no regrets.

After having 4:10's in my automatic and using it for drag racing I wouldn't suggest it. For daily use its fine nothing wrong there but on the track the gearing inside the auto just doesn't work well enough, for me, with the automatics.
I'm going to a 3:55 in my car and I wouldn't recommend anything larger then a 3:73 unless you plan on mainly using it for drag racing then I would go 4:30's.
Just my Opinion...
Thanks, Doug.

Did you talk about the 4.10's with Lidio? When I called him and told him I was going w/ 4.10's and I needed my tune updated he completely talked me out of the 4.10's........that's why I ended up going with 3.73's. Then not long after that Doug posted a topic that echoed what Lidio had told me. I was just curious if Lidio told us two different things?

what would you recommend for a 5spd that sees an occasional trip to the track?
