This is a great upgrade for my 2012 Boss 302 Mustang for wheels whose rubber can't handle the speed and heat of track days. .The problem with this batch is that some of the holes are drilled too big. Bought 12 and only 4 were allowed to screw in, the rest of the screw went in the hole and only screwed in. 8 sent back and now there are 4 more good ones and one was missing a screw. I am sending 4 more as replacements. They aren't punched, I don't know if they should be, but if the holes are made small enough everything works fine. (self tapping screw)
