I bought a full set of control arms and tierods for my car. long story short My S-line has different size tapers on the lower balljoint>spindle than standard A6 cars. So if you need some new lower control arms for your a6 and it's not an S-line package then your all set. Let me know if you are in need and dont wanna pay a million like I did for these.

my e-mail is NATRLBNKLR@aol.com ....names Ben. i'll send you pics asap. NIB German made parts.

was told these fit VW as well
