Won't work. On the small chassis Audi these are designed for, arms are longer from the subframe to the ball joint. So if you want a lot a lot of camber, run these. The arms on the small chassis Audis are approximately 1 inch longer. Also, these are designed to run a 19mm ball joint, not a 17mm ball joint like the Fox.
This pictures shows the difference in the length of the control arms.
