As far as exterior mods go, at least for my car, I think customizing the headlights will make the biggest difference as far as the looks of the car. I don't plan on changing my wheels any time soon so really this for me is the biggest change that will be seen. I did a couple other minor things to the exterior like tinting the car, plasti dipping the emblems black and I added Nismo Carbon B pillar garnishes but thats it. Everyone that has seen the car in person before and after the headlight change couldn't believe the difference so as I said I would highly recommend doing this. You'll be glad you did
