Car looks great man, seen pics of it before but I can't remember where. What wheels are those? It also looks like they have the diffuser wrapped or is that complete aftermarket?

^A diffuser is on the rear bumper of the car, towards the bottom of the car and typically between or around the exhaust tips...let me get you a picture. In the below pic, the black part around the exhaust tips is a diffuser The one on your ride appears to be either black or carbon fiber
