So the stock 2011+ upper strut mounts are garbage. I think one of mine broke because there is an awful creaking noise coming from my front end when I turn the wheel. I guess it's been a problem in the 2005-10 Stangs but it must have carried over to the 11's. I'm in the market for some better ones but those who what to drop their 11+ beware of the upper strut mounts. Maybe my situation is rare but if it's not, heads up.
