I purchased the 512's fron Discount Tire Direct and ran them for about 6000 miles. Very noisy from the first day. All 4 tires feathered very bad on the shoulders and the noise got unbearable. At first, the tire mounter blamed the alignment. The alignment shop said alignment was fine and said that the tire was probably not the best selection for a 4,000 lb. quattro car.

I called Falken and to their credit, they sent me to Sears Auto Center and exchanged my 512's for the ZE-912 at an 80% pro-rated replacement price. The 912's are night and day better. Much quieter, outstanding dry/wet grip and wear has even.

However, the 912's do flat spot considerably (as did the 512's), even after only 8 hours of sitting! My other problem was trouble balancing the tires. The initial tire balance was very poor (the left front had no weights, while the right front had almost 3 oz of lead!) I took them back to Sears for a rebalance that didn't stop the shimmy. So I ended up taking them to a local dealer that had a Hunter GSP9700 high harmonic road force machine, which did a much better job than the Coats balancer at Sears.

IMHO, for the money, the Falken ZE-912 is a great choice for an Audi.
