I would paint the front lip and the rear bumper add-ons white since you already have a black hood, roof, and trunk.
The "rear-valence" is two OEM optional stick-on valences. They should be paint matched to the car.
I'm assuming the hood, hatch, & wing came from a FBP ITR? They should be painted white to match the car. The side molding should have been shaved since the entire car was painted anyways. The front lip would be cleaner white until it gets driven and covered in debri and paint chips lol! A good flexible paint and wax job will help that. The grill needs to be black.
The wheels ruin the car. They're hideous. Go stock blades/swirlies or some used rota's for about the same price lol!
It's a good start though!
