07 GXP Rear Brake Upgrade?

[Leg1tLS4]

Hello everyone,

From my understanding the front brake rotors are 12.9" in the front. How could I manage to upgrade the rear rotors and calipers to kinda match the back. Is there anyway for that? I would like your guys' opinion. Also, if you have any links of rear break kits/calipers, please share them.

you need to run 17 inch wheels or larger to do any of the rear brake upgrades. if you already have wheels that will allow the brakes, i say go for it.

a few have done it here. cant off the top of head recall who they were tho.

Yeah the GXP stock rims are 18". I have 19" rims on there now. So could I just purchase the same size rotors and calipers as the front then? I won't have any fitment issues?

not the fronts, you need the rear brakes off the gxp iirc. id add ss brake lines to the list of parts.
