Will this fit my car?
This listing is for the BMW 3 Series Compact (E46). Chassis code, model year, engine and drivetrain all matter, and Bilstein often use different part numbers for cars that look the same, so check your car against the vehicle table in the description. It is rated for a maximum front axle load of 935 kg and rear of 1190 kg. Compare those with the permitted axle weights on your car's identification plate, not its unladen weight. If anything is unclear, send us your registration or VIN and we will check it before you order.
How much lower will it sit?
About 30 to 35 mm at the front and 15 mm at the rear. That is the catalogue figure: the real drop varies with the car's original suspension and equipment, and a car already on factory sports or lowered suspension drops less.
Do I need new dampers?
No. The B12 Sportline is Bilstein dampers with matched Eibach springs, front and rear.
Can I adjust the height later?
No, it is a fixed drop. If you want to set the height yourself, you need a height adjustable coilover instead. Our guide Bilstein B12, B14 or B16: Which Suspension Adjustment Do You Need? explains the difference.
Can I fit it myself?
Our guide Fitting Coilovers At Home Or Having Them Done covers what the job involves. Either way, have the wheel alignment checked after fitting.
How long does it take?
