The wheels are extremely light. They are about 8.5 lbs each. With a 255/13 A6s that makes for a 25 lb combo. The downside of it is, of course, that lips are easier to bend. And you will certainly see some small bends on them. Hold pressure just fine, balance fine. Has not presented any issues for autocross, but a full disclosure is a good thing.
The pics of them on the car are shown I'm planning to clean them up before posting pictures. Wheels currently have old 255/13 A6s that can be used for fitment as needed. Another 4 old A6s are also available free of charge if someone needs them. I'll start by asking $500 for the set, all reasonable local offers will be considered, of course. Let me know if I'm out on the pricing, too.
