Auryte! I'm not the only one to feel the pain of the new safety check BS! My 315s stick out about an inch, barely noticeable. Passed my Ex with lawn edging from HD, then bought Xenon flares. Might be just me, but they suck! The guys that painted and installed said that the flares were crooked when they first pulled um out of the box, and that they had to let um heat up in the sun so they could make um somewhat fit. The Xenon flares are soft compared to Bushwackers, btw. I got the Ex back and noticed that the double sided tape was starting to pull away from the body. I know that they prepped the surface properly, so I guess the quality of the tape is questionable. I redid the front flares with 3m acrylic tape and adhesion promoter, seems to be adhering so far.
Part of the adhesion problem comes from the fact that the flares have a ¼" lip on the mounting surface - why it's not completely flat baffles me. Not wanting to sand it down, I crossed my fingers that the 3m acrylic tape would work better - in hind sight, I shoulda looked at the flares before giving um to the painter and had the mounting surface sanded flush and level. If they pull away again, I will sand the mounting surface level and try again. Otherwise, I'm getting Bushwhackers!
So to the OP, i wouldn't recommend Xenon flares because of quality and fitment issues!
On a side note, I gotta giggle everytime I pass a truck with lawn edging for flares - HD and Lowes must be selling a ton!
