I have a 99 gt pretty much stock. Lowered, cai kit, borla stinger exhaust. I have been told that 4.10 gears are a bit much for the city driving so I opted for the 3.73. Just lookin to get some insight on my decision? Maybe some comparisons in the rpm range of them both or just opinions. I think they should wake her up quite a bit and I have been told they should put the ol 4.6li. Right in the sweet spot of operation! : ) I look forward to ypur insight and opinions.
