How is the fitment on yours?

Looks like the same one, fitment was very tight. The mounting tabs that attach the diffusor to the under belly of the trunk where there are already machined tapped holes for the stock diffusor pan caused the diffusor to pull down and away from the bumpers stock upper location tabs. I ended up using black self tapping screws and counter sunk washers to make the diffusor push more into the bumper so the lines between the bumper and the diffusor looked more factory. Ive explained this to another member. I can take some pics and post them tomorrow.
