Oh yeah, i did a search for rear end gears, and I couldn't find anything about stock gears. I did find one talking about how high of a gear you could get into one, but that is it. Any info would be appreciated.
GTO's come stock with a 3.46 rear end. Most go to a 3.91
I did calculations using formulas found online (2005 stock 17in tires):
approx top speed in each gear @ 6500 rpm
gear/ratio...3.46...........3.73...........3.91
1st.......... 48.3...........44.8...........42.8
2nd......... 69.4...........64.3...........61.4
3rd.......... 100............93.1..........88.8
4th.......... 143............133...........127
5th.......... 171............159...........151
6th.......... 252............234...........223
Not sure how much quicker the different rears make you
Thanks alot man. Thinking about putting some 3.73s in the future. My 06 is still bone stock, and I can't wait to start doing minor mods. Looking at CAI and exhaust (like most people) for my first mods. Although pockets aren't THAT deep. Going to have to save awhile.
You know, I actually read a pretty long thread about that earlier today on here. Then seeing your post, SloTymer, I went and took them out. Thanks fellas.
