hello guys, im new here so forgive me if this was asked before. i recently bought a 2012 G37xS sedan but i always wanted the big brakes and could never have them. 1, being that the winters (VA) around here make a RWD impractical most of the time and 2, i cannot drive a manual (gasp! yes i know...moving on). so anyway, i figure maybe installing the factory sport brakes that come on the manual version shouldnt be too difficult. though i am not a car tech guy so i would like to know if installing those brakes is possible on an automatic is possible and if so, what parts do i need (factory or aftermarket)?

 

Here you go, and welcome to the site!

And lucky for you the XS 18" wheels clear the big calipers so you're already ahead of most that do the swap
You may need a new spare tire/wheel though, not sure if the XS spare will clear. You can fit this template to the spare to confirm
