2012 GT500 SVT: While cleaning and rotating the wheels, I noticed the original nuts were showing signs of deformation around the points (due to impact wrench usage?) So I bought a new set of 20 that were listed as fitting a GT500, but they are 19mm (3/4") instead of stock 21mm (13/16"). Threaded the same, and on inspection the cone metal-to-metal contact area with stock wheels seems the same (the 21mm looks like a significant portion of metal was not in contact against the rim, and seemed to be exposed to corrosion.)
They do look good.
Any worries?
