Yes. Behind the tire, theres space for rotopax. (This is usually the area where you mount a chopping board) Or you can add brackets to hold a jerry can on the bar. I can send pictures when I use it again. I only put the tire carrier hitch when I go off road.
Yes you will rub with a full 35 without modification. There are two rubbing points. If you go with a more negative offset like 0. It will be the front edge bumper and the front bracket area. I can take pics. If you go with a higher offset like 35 to 45s it will hit the inner bracket area...
I have a jeep and it almost does it every time. The feeling is when the car shifts from 2nd gear to 1st gear. Instead of it being smooth, it feels like you're going into low range. (Going into low range feels more aggressive on a jeep). I had the issue in the GX when I changed to comfort...
I also have 35 inch tires so I think vibration is going to happen lol. I also lowered psi to 30psi and definitely better. I still suspect the KDSS needs some tuning.
