as a general rule, ive noticed the VT/VX is bad, but the VY/VZ isn't quite. not saying there isnt any, but compare a lowered VT to a lowered VY and compare the camber difference.
Dad's VT had Pedder's low in the back and that murdered the tires on 18's. Yet my VS for example, with the same springs, is almost as high as standard, so little wear. as i said, VY's tend to have less camber than VTs
