VEVORUniversal GT Wing Spoiler, 53" Lightweight Aluminum Rear Spoiler Wing, Adjustable Angel Double Row Racing Trunk Spoiler, BGW Drift JDM Drift Black Universal Spoiler

Bought because it was the best deal for the money I could find. I'm building a kart and need maximum downforce on a budget. Biggest concern is the relative flatness of the lower air foil vs the top, so you may need to do a steeper angle than otherwise nessesary.Biggest annoyance is the mounting hardware and cutout for it. I wanted to run higher grade, longer hardware and there's literally no room for a bolt head in the mount guide. Ofc it's aluminum, metric hardware which is basically impossible to find in the States so I had to get creative.

Simple enough to install. I don’t know if I’d expect to run it long term. Good enough to see if you really wanna spend money on a better one.Only hiccup was running into trunk support structure. But as seen in pic just made a bigger hole with step bit to allow a socket to tighten nut flush with trunk lid.
