Out back was a much more straightforward affair, again thanks to APR. We ordered a set of their 14” GT-250 rear wing mounts, installed them on the rear quarterpanels, and measured the overall width of the car as well as the distance between the fronts and backs of the wing mounts. APR customized one of their single element GT-250 adjustable wings with the correct stagger on the mounts and cut it to proper width. To finish things off, APR supplied us with their GTC side plates. The GT-250 and side plates are made entirely of pre-preg carbon laid up in billet aluminum molds and cured in high-temperature autoclaves. No cheap, heavy and inconsistent wet lay-up flea bay stuff here.
