I just installed the exact same setup. 20x9 +1 Fuel Flex and 295/60/20 tires. I am having the same concern when in reverse on the driver side. The tire rubs against the front crash bar. Would you mind sharing what you did to fix the problem? Thanks much appreciated.
I am about to do the same setup. 2.3" stage 3 level, Fuel Flex 20 x 9 with +1, with 295/60/20 nitto recon. It's nice to hear that you are still getting 2.0mi/kwh. Is that a mix of highway/local roads?
