i currently have a g35 and i think it comes with the 3.5 final gears.

im planning on getting a 4.09 but i ahve a couple questions before i do.


1. do you have to open your differential? or can you swap differentials from other nissan cars? and what cars?

2. does the g35 coupe have a sufficiant enough lsd? or should i upgrade

 

1. you have to open it up, cant swap unless someone put it in a z/g diff already
2. i think factory lsd is enough for regular day driving.
