StopTech BMW Rear SS Brake Lines P/N: st950.34531
The stock rubber brake lines on your BMW are okay for street duty but often fall short during spirited or track driving. SS brake lines are more durable than rubber and can provide a firmer pedal feel. These are a nice upgrade over stock.
These SS Brake Lines fit all F2X/F3X and F8X calipers including Blue MSport calipers.
