Bob went out of his way to make my set of 15" pin drive wheels. As mentioned here, they are a die cast wheel that adds strength and will be less likely to leak air from porosity.
The selling point for me is there is extra material cast onto the mounting surface so the back space can be adjusted to really 'customize' your fitment. I went from a set of 17" P&S Engineering wheels to the Vintage 15" with Avons. Hands down, the best investment for traction and looks I have ever spent on the Cobra!
