These brake adapter brackets are a clone of the OEM Audi 8-piston caliper bracket found on the RS4, RS5, RS6, and R8. Audi does not sell this bracket separately from the caliper itself.
NOTE: In general, the rotor used in conjunction with this bracket must match the application that it is being used for. i.e. (RS4 rotors on the B5 S4, B6, B7 & RS6 rotors on the RS6, etc.) Many of the OEM 365×34 rotors have different offsets, and cannot be interchanged from one application to another.
Product Construction: High strength steel alloy, zinc plated
