All right I just went out and measued it again the front is 36 5/8 and back is 39 1/2. So will the 2.8 work then on the Bilstein 5100 Shocks or will that be to tall in the front.
It will look great. Don't worry about the front being higher than the rear.
I think, that's a big "think", that you could lower it down to 2.1 without removing the spring and shock. Ask the installer if that's true and let us know.
