Trying to make up my mind up on gears. I know I'm the first one to do this. 2001 GT auto - 3.73 - 3.90 - 4.10 ? Question - Anybody out there with these set ups, can you tell me what kind of r's your turning @ 75 m.p.h.? My best guess is 3.73 - 24 - 2500, 3.90 - 25 - 2600, 4.10 - 26 - 2700, am I anywhere in the ballpark?
