Grand touring A/S or high performance A/S
The Pirelli Pzero's on the thing now are HORRIBLE.. after about 10k miles they became very "choppy" and are extrememly loud. I had rotated them faithfully etc. so no issues there. they have just over 20k on them now and I can't wait to have my nice quiet A6 back when I replace them (likely with Conti's or Michelins)
