Thanks dude, I'll take some pics after I'm done. 1.5 I think would be pushing it. The SST lift got me almost 2" and it's a significant rub but not on the frame itself. Just removing the mud flap bracket got rid of it but I still want more clearance.
2020 AT4 with readylift SST front lift only, 295/60R20 ridge grapplers, 20x9 +1 offset fuel vandals. Mud flap mod will get rid of the rubbing. Only rubs at full lock in reverse.
