*What size are the OEM Titans?
*Did OEM come only in Anthracite or Silver as well?
*I saw some similar on another car, but I think they were bigger & had an "R" stamped on one of the spokes. Which ones are those?

 

Yes those are titans. they are 17"x7"
They came on the T5-Rs The R got Volans
I dont know the color, but they are like a slighty darker grey.
The ones witht the R stamped is the Pegs from the new V70/S60 Rs.

 

TIPSP is absolutely correct. One thing I might add is the Pegs came in both17" and 18" and they are a little wider. Another thing most people really like the looks of the Titans, but they are fairly soft and bend eaisly. They look great though.

 

Did they come only in one color?

 

I believe Yes.

 

yeah they bend really easy!
