what to do first?
Howdy, I just got a 2003 GT. I was wondering what was more worthwhile doing first.... Switching out the rear axle ratios, or improoving the air intake, (wide mouth throttle body, mass air intake or whatever, high flow manifold, whatever else)
Welcome. Gears will give you the most seat of the pants increase in acceleration. However, combined with improving the air flow through the intake and through the exhuast will compliment each other nicely. Just dont go too big or you will be wasting money and possibly sacrifice performance. I suggest you check the model specific forums to get a better answer for your car.
