So after some searching I finally managed to source a genuine lip for the GTR bumper.
Its currently on the way to me from Japan and once it arrives the front of the car, bonnet, grill, bumper and wings will be getting painted.
Im currently debating whether to wrap the grill in carbon or else leave it the colour that it is and also add a rocket dancer lip like the one below.
The car will finally be looking the way I want it!
