I noticed that the front sits lower than therear. The back is 3/4 of a inch taller in wheel gap from the center of the wheel to the bottom of the fender lip. the gap in the rear is 16 3/4 inch. The front is 16 inches even. I think that the extra weight of the supercharger system is pushing the front end down a little. I am going to pull the rear coil and cut about 1/16 to 1/8 of a coil off to lower the rear to match the front. I need to drop the rear 3/4 of a inch. I hope to have it done tomorow along with geting my 235 60 16 tires.
