I'm looking at some 5Zigen FN01R-C (c=cast).

Also, cast vs. forged? I think forged is supposedly better, but not sure.

 

It's been discontinued. What is your source?

Otherwise you can also check out Enkei Racing wheels from tirerack.com

You did not mention which wheel size, width and offset you were considering.

In general Cast Alloy is cheaper to make but also can weight more to get similar strength to a Forged wheel. But even forged wheels that cost more can break. You get good strength with less weight when forged.

It's a co-worker who sold the car last fall and still has these wheels. They are sitting in a garage. They are 17", but still awaiting information on width and offset. Thanks for the reply.
