Eibach Pro-Street-S Coilover Kit — BMW 1 Series M135i / M140i (F21)
Pro-Street-S is Eibach's height-adjustable coilover system — stainless steel construction and a much wider window of ride-height and handling adjustment than lowering springs alone can offer.
Technical specification
Lowering: 25-50 mm front / 30-55 mm rear (M135i/M140i); 30-55 mm front / 30-55 mm rear (xDrive)
