Recently acquired a 93 RX7. I have converted to a single turbo and am interested in adding a rear wing. The original rear spoiler has been removed so there are no mounting holes. There are a lot of wings advertised but really want something that will be useful and not just for show. Car would fall probably into SSM as it still has full interior and the only body mods are the removal of all emblems. The exhaust, turbo FMIC, porting and other mods will keep it out of any other class. Probably will used for some auto-x but also for time trials.
Just looking for some realistic suggestions on providers. Don't think I really need carbon fiber but wouldn't rule it out. Aluminum should be adequate.
