I think you need to look closer at the picture. The rear wing is floating about 10 feet above the rest of the car.The wing is correct.
I can confirm one thing on my end. If I install the original F1 2011 mod, the wing is in the right place. If I install the updated version that Tabs did, the wing starts to float. Hope someone can help me because I love the way the mod looks with Tabs edits and would love to use it instead of the original.
