For a 2018+ BMW 3 Series (G20/G21/G28) that sees track days as well as the commute, the SF Racing Track Coilovers add firmer valving on top of full height and damping adjustment. This version is listed for RWD models.

2018+ BMW 3 Series setup details

Expect true coilovers at the front and a divorced rear, where the spring and damper sit in separate locations as they do from the factory. Damper bodies are 52mm front and 50mm rear. It comes with 8.3 kg/mm (about 465 lb/in) springs up front and 11 kg/mm (about 616 lb/in) at the rear. Damping is 1-way: a single knob with 32 settings changes rebound and compression together, which keeps tuning quick. The front top mounts are aluminum with rubber bushings, with aluminum camber plates with pillowball bushings available as an option. At the rear, the mounts are aluminum with rubber bushings.

Key features

  • Monotube damper design for better heat control and fewer leaks
  • 32 damping settings on a single knob that sets rebound and compression together
  • Bolt-on install with no modifications, unless the notes below say otherwise
  • Adjustable ride height, roughly 1 to 2.5 inches below factory per SF Racing, while keeping suspension travel
  • Separate lower-mount (length) adjustment, so height changes don't preload the spring
  • Anodized T6-6061 aluminum top mounts, spring perches and collars for corrosion resistance
  • Zinc-plated shock bodies for rust protection
  • SAE9254 cold-wound springs
  • NOK seals and Italian IP damping oil (20W)
  • Built-in dust boots and bump stops

Who it suits

Best suited to cars that do track days, autocross or spirited back-road driving, and owners who accept a firmer ride for more control.

SF Racing coilovers for your BMW 3 Series: what to know

Coilovers combine the spring and damper in one adjustable unit. That lets you choose your ride height on the BMW 3 Series and, on kits with damping adjustment, tune how firm it feels.

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 2018+ BMW 3 Series RWD (G20/G21/G28). 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 SF Racing. 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.
