All sorted with my rear inner guards, actually it was the inside of the 1/4 panel, with the help of a mate i took the plastic guards of and just folded the sharp edge up out of the way, a small amount of paint chipped of so we hit it with underbody tar, let it set and replaced the plastic trim. Thanks for the advice i hadnt noticed this was what was damaging my tires until you mentioned possible damage to tires. That should sort it out under flex and when i get the lift she will be right for sure.
