Well I measured the distance between the top of the tire and the fender and my back is about 1.75" off and the front is like 3" off
... I'm not sure if that's because I have about weight in the back due to my sub box and driver or because my car's gay. I also have 17" rims. I'm thinking about doing it myself, I can get a spring compressor. Then again might have someone else do it, we'll see.
