  • Model years: 1999-2008. Check your car's year falls inside this range.
  • Factory adaptive dampers: if your car has electronic or adaptive suspension, check whether the listing covers it or needs a cancellation kit.

Parts that usually go with it

  • An alignment. Any change in ride height changes camber and toe. Set your final height first, then align.
  • Camber and toe adjustment. Bigger drops often need adjustable arms or camber plates to align properly. See alignment and camber kits.
  • Wheel and tire clearance. Check clearance at full lock and full compression, especially with wider wheels. Our ride height and wheel fitment calculator shows how much drop and offset change you are planning.
  • The right spring rate. Compare the rates listed here with what our spring rate calculator suggests for your car's weight and use.

Questions about BMW 3 Series coilovers

Will this fit my BMW 3 Series?
It is listed for the BMW 3 Series. Check your year, model, drivetrain and chassis code against the product title. If anything is different, contact us and we will confirm fitment with the supplier before you order.
Do I need an alignment after installing coilovers?
Yes. Changing ride height changes camber and toe. Set your final height, let the suspension settle, then get the car aligned.
How low can I go?
It depends on the adjustment range the brand lists, your wheels and tires, and how you use the car. Most cars that are driven hard work best with a modest drop that leaves enough suspension travel.
Where do specs and warranty details come from?
From Lower HQ. We sell parts from several brands and suppliers, and each one sets its own specs, lead times and warranty terms. The product details above are the latest we have.
