got a set of wheel locks from bmw dealer for my x3...the head is larger than the standard head and dosnt fit the lug wrench...the tapered part under the head sticks far out from the wheel compared to the standard screws...i think these may be wrong...are their various sizes made in wheel locks as these were the only ones i saw listed...just checked the ones i got are for 2005 but i think thy may be different for 2006's
