This is SF Racing's track-oriented coilover kit for the 1999-2003 Audi S6 Quattro (C5/4B): height-adjustable, 32-way damping and valving tuned for hard driving at the circuit or on back roads. This version is listed for AWD models.

What you get

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 18 kg/mm (about 1008 lb/in) springs up front and 12 kg/mm (about 672 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 dampers, which shed heat well and hold their damping under hard use
  • 32 damping settings on a single knob that sets rebound and compression together
  • Zinc-plated shock bodies for rust protection
  • Cold-wound SAE9254 spring steel
  • 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
  • Independent lower mount adjustment keeps spring preload and damper travel where they should be when you change height
  • Anodized T6-6061 aluminum top mounts, spring perches and collars for corrosion resistance

Important: Sedan / Avant.

Who it suits

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

About this coilover kit for the Audi S6 Quattro

Coilovers combine the spring and damper in one adjustable unit. That lets you choose your ride height on the Audi S6 Quattro and, on kits with damping adjustment, tune how firm it feels.

Fitment notes

  • Listed for: 1999-2003 Audi S6 Quattro AWD (C5/4B).
  • Model years: 1999-2003. Check your car's year falls inside this range.
  • Chassis code C5/4B: the same model name is often used across several chassis codes, so match the code, not just the name.
  • Drivetrain: AWD. AWD and 4WD versions often use different suspension parts from 2WD versions of the same car.
  • Factory adaptive dampers: if your car has electronic or adaptive suspension, check whether the listing covers it or needs a cancellation kit.
  • Specs, lead time and warranty come from SF Racing and can change. The details above this guide are the latest we have.

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 Audi S6 Quattro coilovers

Will this fit my Audi S6 Quattro?
It is listed for the 1999-2003 Audi S6 Quattro AWD (C5/4B). 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.
