Anyone use these? Do they really help lessen the chance of damaging wheel finish when taking on/off lugs? Are they worth the extra cost?

Some examples:







"Used throughout Japan by many race organizations, these are extremely lightweight and strong. The special feature of this open ended lug nut is the two-piece design which allows the lug to spin freely from its tapered centering ring. This allows for a much tighter and snug fit, and will keep you from stripping the paint from your wheels during installation and removal. For added security, these lug nuts can only be removed using the included wrench adapter."

Not sure about the Project Kics R26/R40?

 

Look pimp.

 

I was going to get these as well and still thinking about it. I believe the purpose of the floating piece is to not damage the inside of the rim where the bolt touches the rim when tightened.

 

the McGard spline lug nuts have floating heads too....
