Torsion Bars (Raising/Lowering)

Thanks guys I thought it was probably a bad idea to do so. He's all about "the look" with little care about safety (very thick headed).

Also, while we're pooh poohing his ideas, he's got bias ply tires up front and radials on the rear. From what I was told, and can't remember why, this is not to be done either. Why is that?
