The 2010 Smart fortwo BRABUS cabrio bolt pattern is 3-112 mm. This means there are 3 lugs and the diameter of the circle that the lugs make up measures 112 mm or 4.4 inches across. To get a close measurement of your 3 lug bolt pattern without a bolt pattern tool you should measure from the center of one lug to the center of the lug across from it.
