I have a thin rear diffuser on my Crossfire as an alternative to the OEM and Startech.

I have had several people ask for one like this but made a little thicker. I have found a source to make them. They would be painted grey primer (similar to the OEM) and you could leave them that way or have them painted to match your Crossfire's body color (or contrast!)

The would be a fairly simple bolt on using some of the existing mounting points and self tapping screws for the rest. This mounting method is VERY strong. I have had mine on for around two years at speed up to 130MPH (on the track of course) and they are a solidly attached as the day installed. Quick and easy install with instructions and mounting hardware.

Please indicate which you like best. I am shooting for a sub $120 price point plus $20 S&H to the continental US via FedEx Ground 4 day.
