15x6.5" +45mm offset
4x100 Only (67.1 hubcentric)
Rota Circuit 8

Would these work with a 205/50 tire?

 

Oops.. Circuit 10.

 

Yes.........

 

What about the hub?

 

As with most aftermarket wheels, you'll need hubcentric rings.

 

Do you really need a hudc..ring, I just purchase Drag Wheels DR-23 try them on for a short time waiting for the spring to arrive. I had no vibration the fitments felt very tied with the cone shape lug nut.

I read a few post and it seem not necessary in every case your opinion?

 

I never said it was necessary for every setup. I said that they are used for most applications. It just depends on the wheel. To find out for sure, contact your local vendor and ask them if you need them or not.
