Message	Alright I have been wondering this for a very long time so I finally decided to post this question. What are the aerodynamic effects of installing a twin z rear bumper type 1 or 2 that has an obviously lower profile than the oem bumper. Does the lower profile catch more air inside the bumper causing more drag? Is the lower profile better suited aerodynamically to a larger diameter rear wheel? Also looking at this very good comparison photo it appears the angle between the road and the bumper is much more aggressive/steeper than the oem bumper. How does this effect aerodynamics?
