I want to know would it be possible to run this bumper on a 2011 & up model even if I went back to a pre facelift grill.

 

I am running the TS style bumper from baySide Aero on my 2008 G35s.
You would need to change your grill and your heaadlights, not worth it.

 

I'll trade my grill and headlights with you if you want to go to the older style.

 

ha same here!

 

ill trade you my lights and bumper as well.
this is the first time i have heard of anyone wanting to switch to the older style, just get the sport bumper if you dont already have with a nice lip and call it a day!
