Thanks for all the responses. I have a automatic , and for gears I was thinking 4.10's , but will I burn a lot more gas ? Cause I do mostly highway miles. And as a budget ,I just save up for what I Whant or need.
ok i have a 2000 mustang gt with 107k. I have Dual flomasters with 3inch tips, other than that stock. What would you guys recomend performance wise. I was thiking tuner, gears, also what kind of gears?
