get 4:10 and changing your gears is not gonna change your posi rear end.

SilverGTV8

4.10 are to much gear for a s/c.

Is it a factory button? if so that doesn't control posi, it controls the cars reaction to a spining tire.

MikeHawke

Yeah, that button doen't control the posi...it's just for the traction control.

No worries dude...just get the gears for your year of GT and you will be fine.

he didnt tell me he was going FI if you are than get 3:73

callmecobra

go with 4:10s, 3:73 suck. and that switch allows the ecu to pull fuel and timing, so it wont spin.

yeah go with 4:10 you can never have too much gear lol. just get really good tires
