I need BOOOOST!!!!!!
what exactly does this kit do? focus power does it and im seeing a kit for it on ebay. does it regear the tranny or something? how exactly does it work. i know a decent ammount about troubleshooting and simple performance mods for engines but tranny, NO. last time i tore into a tranny it was the tranny of a 95 cadillac deville. we opened it up and i swear it was like looking at a brain. but anyway im getting off topic. what is the 4.06 final drive kit? what does it do exactly? and what kind of performance gains would a person get with it in combination with a decent LSD?
