Rims and bomex bodykit questions

I currently have the bomex front bumper and am looking to get the skirts and rear. Here is a current pic.

I noticed that there are many ways to paint the rear bumper and I was wondered which looks best.

Here it is solid red

Here the back lip is red but underneath it is black

Here the lip and under it is painted a different color from the car.

Which would look best for a red car? If not solid red, the other color would be black?


Also I currently have 17 in rims on and would like to get 18s, anyone know what kind of rims are on the below picture?

Also, what is the difference between 215-35-18 and 225-35-18 wheels?
