Hello all, first post!!! I've been trying like crazy to find compatible lug nuts for my 2006 GXP. I think when I got new tires they used the wrong size socket because I had to replace some due to the outer coating splitting. Was getting some warranty work done at the dealer and they replaced five on one wheel for $12 a piece! Anyone have any ideas for me? And correct me if I'm wrong but don't the front and back wheels have diff sizes of lug nuts? Any help would be appreciated!
