I pulled of the diffuser and reinstalled it “better”. Reworked the slots in the bumper, so the diffuser snaps in place better.
Made a few more brackets to mount it more solidly. Now you could swing from it.
Also replaced the GP rear black bumper trim with stock trim, because it works better with the GP2 diffuser. Spent quite a while trimming it to fit perfectly. Now looks totally OEM.
