I am a little bit afraid of new gears...I would like to try driving a Mustang with different gears to see what the difference is before I make a decision.
I also do not think that I can install them myself...I would like to learn but I think it might be a little too advanced for my mechanical skills. I did my own cat back and that is probably where my mechanical expertise would end.
How about a set of under drives? They're a snap to install, and won't break the bank. Although I really recommend saving up for a rear gear swap at the same time. It'll feel like a whole new car.
