Comes with everything shown! Including the hub, plastic accordian looking cover, to shims, two types of horn buttons, and some ring who's purpose is described on the box in Japanese. Good luck. Works great on or little race Miata, no need for a 2nd.

Hub is 2.75" in length from face to face, with two 6-bolt patterns. I know it fits my MOMO (so Spacro too) and my friend's Nardi wheel.

 

Not to be an ***, but these go for $14 shipped brand new now.

I see. I couldn't find them online, all I was going off was someone saying they were $40 shipped.

Price lowered to $15 shipped!

 

If you've still got this ill cop it if you can do 10 shipped?
