Decided to replace the two piece OEM lug nuts with the Gorilla Acorn Bulge lug nuts, part # 41187, as recommended in several places in the archives. Having received and inspected the aftermarket lug nuts, I'm concerned that the contact area between the nut and Wheel appears to be about 2/3 of what the stock nut provides. Although I don't like the two piece construction of the stock part, I don't want to increase the stress on the BBS wheels and possibly cause a crack. Has anyone using aftermarket lug nuts had any problems with their wheels? Are there any opinions from the track crowd? Is there another aftermarket, one-piece solution with the same contact area as the OEM part?
