Duane,
Something else to consider—I researched spoilers, wings, etc. for several weeks before I made the purchase. I didn’t buy the Cosmo wing because I thought it was the best; I purchased it because it seemed to be the best fit and the best all-around component for what I was attempting to accomplish. The majority of my research went into the location of the wing’s mounting points and the distance between the mounting points (where the wing bolts to the uprights, i.e., support brackets supplied with the wing). In short, I wanted mounting points as close as possible to the spreader bars on my roll cage so I could use the Coleman Racing and Longacre hardware accordingly. You can purchase straight from Cosmo, but their eBay deals are usually much better. Here’s a link to their web site:
