For anyone interested Erebuni has one 020RW wing left in stock that was part of a custom build. The wing is a cup style designed specifically for the 928 but requires minor fitment and will need to be painted. It is a functional wing with about 10 degrees of flip off the tail. Construction is ABS plastic and self tapping screws are used for attachment (supplied with HDW and instructions). Measurements are 15" W x 56" L. The front of the perch is 3" H and the rear is 7" H. This is a single molded piece. Erebuni designs custom wings for Porsche and other cars. Here is the link: http://www.erebunicorp.com/clearance/pr928.htm

Proceed at your own risk. Erebuni will not build anymore of these wings unless a very large order comes through (not likely). Clearance item. I am not affiliated with Erebuni in any way.
