Listed for: 2012+ Mercedes-Benz SL55 AMG (R231)Fitment notes & questions

If you want a lower, tighter 2012+ Mercedes-Benz SL55 AMG (R231) without a harsh ride, the SF Racing Sport Coilovers are made for that job: street use, adjustable height and 32 damping settings.

How this kit is set up for the 2012+ Mercedes-Benz SL55 AMG

Both ends use a true coilover layout, with the spring sitting on the damper body at every 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.

Features

  • Monotube damper design for better heat control and fewer leaks
  • 32-level damping adjustment, rebound and compression combined on one adjuster
  • Adjustable ride height, roughly 1 to 2.5 inches below factory per SF Racing, while keeping suspension travel
  • Independent lower mount adjustment keeps spring preload and damper travel where they should be when you change height
  • T6-6061 aluminum hardware (top mounts, perches and collars), anodized against corrosion
  • Zinc-plated shock bodies for rust protection
  • Cold-wound SAE9254 spring steel
  • NOK seals and Italian IP damping oil
  • Built-in dust boots and bump stops
  • Bolt-on install with no modifications, unless the notes below say otherwise

Who it suits

Best suited to daily drivers and weekend canyon cars where ride comfort still matters.

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 Mercedes-Benz SL55 AMG coilovers

Will this fit my Mercedes-Benz SL55 AMG?
It is listed for the 2012+ Mercedes-Benz SL55 AMG (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.
