I have wing risers myself. The only issues I had with them were getting them from the manufacturer, Boomba. First they sent Focus Risers, then the right ones but one broke, THEN wrong color. After a month and a half from start to finish I finally had them. The product itself is high quality, and still seem tight. I actually got a very thin foam pad that I screwed in between the riser and the car, to prevent damage.
