My wheels have a center cap over the lug nuts, but the factory lug nuts are a little to tall. I can't snug down the center caps. I bought some generic Tuners lugs that thread on great, but are even taller than the stock lug nuts. not much taller, just enough to make it impaossible to get the center cap to stay own. I found some acorn style wheel locks that fit in there great, but they aren't metric. question is, does anybody know where I can get a low profile set of lug nuts that use a key/adapter for security?
