I don't know that 6" lift would be enough for me to consider buying a set. I think I'd have to have more lift to really appreciate them, although on my Charger 6" would be enough to remove the belly pan and THEN I could reach a spot on the frame with my hydraulic jack.

The other thing I look for when considering a set is that they advertise that they don't slide. Some are known to slide.

Facts are stubborn things.
