I`ve got two boxes with black lug wheel nuts, which I have to use for with my OZ`s(I didn`t have time to change them yet.)
The brand name is TAK and it says on the box that they`re for Toyota, honda, mazda etc.
Just go to any car shop and ask for size m12xp1.50
If you still can`t find any, than mail me and I might be able to ship you some boxes.(sending will be a bit pricey though, one box is $5 which contains 16 lugs)
