I want to gears in the next couple of weeks( 3.55's), but im a little scared of doing them myself. I've never done gears before and heard they are tough to set up.
I got a hoist available to me at the Ford dealership were i work. I might get one of the technicians to give me hand. I've just started my first year as an apprentice, If i do it myself it would probably be a good way to learn.
Yes, you should be about a tenth or so quicker in the quarter...and yes gears will definately help you out a ton. i just got some 3.73's put in a couple weeks ago and it is the best mod i have ever done. replace your t-lock clutches and bearings when u do the gear swap...and make sure u spend your time and do em right! good luck man
