Re: What Gears 3.55 or 3.73?
Hey Jarrett? I just bought my 98 GT a month ago and am pretty sure my gears are stock. Mine runs about 2100 RPM's at 70mph. I drive 38 miles one way to work, 80% highway, so gas mileage is important to me. It get's 24-25 mpg's right now, and I'm VERY pleased with that. Just out of curiosity, what RPM does yours run in 5th gear at 70mph?
1998 Mustang GT, 5 spd, 17" wheels, all stock (I think)
