Hello all. I own a 2009 Audi A4 B8, 3.0 TDI. After 3000 kms I noticed that after a bit of braking I`d get heavy vibration in the steering wheel at around 100-120 km/h (only when braking). I went the to Audi service and the brake discs where changed under warranty. The new discs after 3000 miles behave the same after they get a bit hot more braking. Before this car I owned a B8 2.0 T.D.I. and I had the same problem with the brakes after 15000 kms. The brake discs on the Audi seem to be of very low quallity. So ... please tell me is there a chance to find B8 sport brake discs, I`ve been searching like hell and nothing shows up, except the MTM brakes which stand at 5000 with installation, but I`d only want to buy some new discs. Thanks for your help. P.S. I do drive a little bit rought.
