My good friend Chris bought a new wrangler 4xE a few months back and has been anxious to upgrade it from its stock wheels and tires. I'm excited to see how the Jeep Wrangler Rubicon 4xE does with larger 37" tires and a 2.5" lift. Will it adversely affect the gas mileage and performance? How much?

Teraflex 2.5" Performance Spacer Lift. (Front and Rear Bump stops are needed because it is a Rubicon.)
