What does a relay in the trunk have to do with the front grill in terms of RS swap? Also what exactly are the shutters for the diesel model and doesn’t the RS have its own version of the shutters I would like to do this swap as if it were stock and want to be 100% informed as to any and all caveats. Thank youI don't really want to lose the shutter system. If it mounts to the bumper, it looks like it all clips onto the lower grille. I wonder how difficult it would be to modify/swap over to an RS bumper. I'll keep my eyes out for one I guess and compare mine to it.
