i have a 99 GT, just wondering what the difficulty is in changing the gears out. do i need to have bearings pressed onto the pinion or anything. i was looking at the kit from RPM Labs but dont want to have to pay a shop to put them in. i do know my way around cars but mainly sport compacts, and never have dealt with the rear end of a stang.
also i was wondering how easy it is to use the flash tuner that comes with it..
anyone HeLp!!!
thanks guys

 

its so hard to do you should just take it to a mechanic back lash etc if its not done right you will burn them up

 

Let a pro do it. There is no room for error.
