Hmmm fasinating. Those lug nuts are longer, so more of the key fits into them. This equals more contact, less likely to be stripped etc... Hmm I like those, but I will buy those for the Enkei rims, and upgrade my current TSW nuts. Reason being I am going to be doing this 2x a year (in theory, 2 HPDE per year), so whatever takes the wheels off the quickest is nice.
