i put 15s off an slt durango on my truck and had to grind the upper control arms to keep them from rubbing

 

For some others they had to grind down the banjo bolt. A wheel spacer would help too.

 

Mine rubbed on, if I remember right, the fluid bolt (the one that connects the brake line to the caliper).

 

I also have the next gen Dakota 15x8 wheels on my Dakota 4x4 (factory height). I filed the control arm/fluid bolt (can't remember which) about 2-3 mm to clear the rubbing during the tightest turn. The spacer option (Crazy4x4RT) should also do but more costly.
