To add a little info on my experience. I have the TRD Pro wheels with 1.25 spacers and SPC UCA’s on a 18ORP with 285’s. I get rubbing on the back fender well. I took off the mud flaps and still get rubbing on the weld joint behind the mud flaps.
I’ve had the alignment tweaked and still get some rubbing at the extremes. I’ve done the fender liner mod and still get some slight rubbing there from pushing my wheels forward during he alignment. I haven’t decided if I want to keep tweaking or just give up on the wider stance. I’m unwilling to cut into the fame to prevent the rubbing there and my alignment guy says pushing my wheels to far forward will affect the steering to much.
