Can you tell us more about your setup? Namely suspension, control arms, and caster setting. I'm also curious. I haven't had any of those issues with 34's. I'm not racing competitively, but I've pushed it fairly hard and haven't found any issues with rubbing or contact in the front (outside of the normal mud flap and BMC that were necessary to fit).
My setup is stock LCA (with KDSS), stock bump stops, stock wheels sometimes with 1" spacers, sometimes without, Fox 2.5" front coilovers, and JBA UCAs. I set my caster pretty high - around 4.5 - and I'm set at around 2" lift height, but I've gone everywhere from 1-3" height over the years.
I do actually get some minor rub on the inner fender liner in the rear in the whoops at speed if I push it. But nothing up front.
Longv, What suspension and lift were you running when your 34 slammed up inside the the wheel well and created the dent? What extended bump stops are you going to put on?
Thanks for sharing the info.
At the time dobsinsons 2.5fr 2rear, dirt king upper arms. Ripped out both fender liners, pushed back and bowed out the fenders by the bottom near the door. Bent spindles and/or lower control arms
My current set up is fox 2.5 all around, dirt king lower kdss arms, wheelers offroad bumpstops, new spindles with gussets welded in.
