I have a complete set of RS4 Brembo Front Brakes and Lucas-Girling rear brakes for sale. The RS4 brakes were developed jointly in house by Audi's quattro GmbH, not by Porsche as with its predecessor, the RS 2. At the front, they were manufactered by Brembo in Italy, radially vented and floating cast iron discs, 360 millimetres (14.2 in) diameter and 32 millimetres (1.26 in) thick, with double-piston floating calipers. In the rear they were manufactured by Lucas-Girling in England and had 312 millimetres (12.3 in) by 22 millimetres (0.87 in) discs with a single-piston floating caliper. The RS 4 needed less than 50 metres (160 ft) to come to a full stop from a speed of 110 kilometres per hour (68 mph). My cell is 925-989-0722 if yu want to discuss the offer.
