I would recommend Gorilla brand Spline lug bolts. They are relatively cheap and stay shiny forever. They are pretty light and utilize a full set of matching lug bolts instead of one wheel lock with regular lugs per wheel. Available in 20 pc. 14x1.5mm for VR6 and 16 pc. 12x1.5mm for G60. Available in ball seat(most BBS wheels) and cone seat(most other aftermarket wheels). But like all theft deterrent lug bolts, for every set on a car, is a thief with the key to remove your lug bolts. It doesnt matter what type of lug bolts you have. :D
