I think it looks good as is but removing the spacers should work well too. With 33s I only had to adjust the steering stops a bit, not enough to really notice any change in turning radius, so with 31s the adjustment should be minimal. The main problem with the tires sticking out will be that the rear flares will start to get erroded on the front edge (the front edge, strange as it may seem). Mine got that way from when the YJ had 30s that stuck out a bit.
