Hub Ring Size????
 

I bought a set of 16" Kosei K1's from a friend when he sold his teg and I just realized that he didn't give me the hub rings...or never had them on his car.

What I need to know is what size hub ring do I need to order OR how do I find out what size I need? I never had to buy hub rings separately before, they always came with my rims when I bought them.

Any help would be great

Thanks
