I think these are part of the aerokit, but I want to get just the rear pieces. Anyone?

 

check ebay they have carbon fiber ones from taiwan for $300

 

Have you seen a straight on shot of the back with these on? they look out of place!

 

I was also looking quite awhile for these used since I didn't feel like they were worth close to $500.

Finally decided to go the rep route as one of the places are having a SEMA sale on them right now for under $300 for FG versions. Saw the CF ones from Taiwan but didn't want to deal with any long ship times or duty taxes. PM me for info.
