Lug Adapter things?

Anyoen ever used one of those Lug adapters? They change the lug patterns, they are like an steel circle drilled for your lug pattern but then are drilled and have lugs on them for a diffrent pattern? Anyoen know what Im talking about?

I used them on my old VW bug before. Mine were made out of cast aluminum though and a wheel fell off when I was driving down the road! The ring broke alowing the lugs to come out. Make sure you buy steel ones r atleast billet.

yeah those things are very dangerous, i wouldnt recommend them to anyone, even my worst enemy, also they make your wheels stick out further like a spacer so no tucky tucky
