I am switching gear ratio's because pretty much no matter what this car has to see a freeway and i'm tired of buzzing on the freeway at 3000rpm going 65. My question is can anyone give me an idea on how much of a difference this would hurt me performance wise? My Goal is to achieve a 12.7-12.9 with this car and i was wondering if i was crazy to think this was possible with either set of gears.
