I bought my FiST used and it came with a wing(spoiler) riser kit. I didn't like the looks of it and you might. The previous owner was nice of enough to leave me the original hardware so now I am back to normal. I don't know who made this kit, but the spacers are all nice CNC black anodized aluminum. The two center risers reuse the existing hex bolts. The 4 outboard risers require the included hardware.
