This left-hand front ventilated and drilled brake disc is designed for the BMW Series 3 E36 M3, whether in Saloon, Coupé or Cabriolet versions equipped with 3.0L (code S50B30) or 3.2L (code S50B32) engines, from September 1992 to August 1999. Its dimensions are: diameter 315 mm, thickness 28 mm (minimum thickness 26.4 mm), bolt circle 5x120, bore 79 mm, weight 7.7 kg.
