Am currently running a set of older Kumho 33x12.50 tyres which have a tendency to rub at full compression on the left front guard and inner rear tubs, even with 2'' lift. Understanding is that an adjustable panhard rod for the front may better align the front axle (one is on order) and sort out the front, however was wondering what everyone's thoughts were on correcting the rear rubbing?

Spring spacers have been considered as well. Am currently looking at pros & cons of both options.

Thanks in advance.
