OEM RS5 wave rotors, free to good home. FRONT.
 

Just pulled these, they are half a mm from passing street inspection in the US. I don't know for a fact but maybe someone will educate me: I imagine you can get a track day or two out of them.

I used P/N 4S0615301B to source the replacements. Pick up feasible in the 703/202/301 area codes. Actual shipping otherwise. It was raining when I pulled them.https://cimg1.ibsrv.net/gimg/www.aud...f3d4bafdce.jpg

Full retail, $900!!!! EACH.

Oh and
 

Apparently these are also R8 rotors....
