I did get 18x9s to fir with 6.11 backspacing although some grinding of the UCA was required. Seemed to me just by grinding the outside a little, and the hat on top of the ball joint, it really didn't effect the structure of the UCA much... Thinking of going with coilovers but not sure if they will buy me anymore room or not. The wheel does have full range of motion without hitting anything.
