Upgrade the stopping power of your Audi B3 Coupe/90 quattro. With these precision-machined durable 1018 steel brackets, rear 4-piston Brembos from the Porsche Cayenne can be mounted to the rear of the CQ/90Q using large 323mm Audi A8 front rotors. The brackets are designed to accommodate our upcoming parking brake calipers as a direct bolt on upgrade. Includes mounting hardware. Pairs best with our 18Z bracket kit. 
Note: the pad retaining pins on the calipers need to be ground down 2mm each for clearance to the A8 rotors.
*ensure you are using Audi B5 A4 quattro rear hubs for these to fit.
