Listed for: 2012+ Mercedes-Benz SL-Class SL400 (R231)Fitment notes & questions

SF Racing's Track Coilovers for the 2012+ Mercedes-Benz SL-Class SL400 (R231) use firmer, track-focused valving for drivers who want sharper response and more control, while staying usable on the street.

2012+ Mercedes-Benz SL-Class SL400 setup details

Front and rear are both true coilovers, which keeps ride height adjustment simple and precise at each corner. Damper bodies are 50mm front and rear. It comes with 14.5 kg/mm (about 812 lb/in) springs up front and 10 kg/mm (about 560 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. 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
  • SAE9254 cold-wound springs
  • NOK seals and Italian IP damping oil (20W)
  • Built-in dust boots and bump stops
  • 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

Who it suits

Ideal if body control and response matter more to you than the softest possible ride.

What else to plan for

  • 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 Mercedes-Benz SL-Class SL400 coilovers

Will this fit my Mercedes-Benz SL-Class SL400?
It is listed for the 2012+ Mercedes-Benz SL-Class SL400 (R231). 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.
