I have the Statin Stretch cover by Cover king. It fits my car perfect and i have the Rideskinz Aggressor bumper which is 2 inches lower than the stock SS bumper. So in therory you should have no issues with buying an SS cover.
Oh and if you choose Cover King, Buy through someplace other than their actually website. I got mine from Cover King on Amazon for half the price they were selling it on their own website.
