I picked up a set of 17x7.5 Kosei K1s used and was wondering if I need hub centric rings for them or am I good to go as is? Also, do I need to buy new mounting hardware?

I'd check myself on fit but they're getting powder coated right now (Pearlescent Steel Gray - kind of a charcoal/gunmetal) and I can't test fit until they are returned and I'd rather have everything ready for them to be mounted when I get them back.

You will need hub-centric rings; I bought my Koseis used and the rings came with them.

BTW - get metal rings instead of the plastic ones, they hold-up better through all the wheel changes.

Any idea what size?

Call the Tire Rack and ask for Alex. He'll have the answer.

The answer is 56.1mm inside dia. and 73mm outside dia. Alex has them.

 

Excellent! Thank you.
