There are 18x9.5 ET35mm with 12mm H&R spacers. ~18lbs each. Gun-metal color.
I don't have pics (and can't take any right now because I'm at home in Austin and the wheels are in a garage at TWS), but I will say they are track wheels, not for show. Covered in rubber marks, tape from wheel weights, etc. Nick on the inside from making space for my own apexes
My strategy is to replace a wheel once they can't balance it anymore. That has happened to me once, so I bought two new wheels - hence why I have a spare wheel.
They work great, and are easy to find/buy spares.
