Roderick wheels are made by
MRR which have a great reputation in the Euro market.
I ran a set of MRR on my old A3 for almost 5 years and never had one bend/crack or any issues.
The RW5 is a Porsche specific wheel, but the RW7 can be made to fit a 370Z, although their recommended setup is 20x8.5 20x10
Let me know if you are interested and I can help you out!
