im not 100% on this but I believe some racing sactioning bodies do not allow aluminium wheel nuts

 

I like the Volks alot and wanted them to match my rims but the shop only had the kakigzumi (or whatever) and I got them for $50. I was thinking of the Volks but I noticed some titanium ones for $100 at superautobacs which makes more sense to me. Instead of getting them for the matching blue i'd get super strong lugs that can take an impact gun beating.
