Listed for: 1997-2004 Audi A6 FWD Avant (C5/4B)FWDFitment notes & questions

SF Racing's Sport Coilovers for the 1997-2004 Audi A6 Avant (C5/4B) are a street-focused kit: they lower the car, let you set the exact ride height and give you damping adjustment while keeping a ride that works every day. This version is listed for FWD models.

How this kit is set up for the 1997-2004 Audi A6 Avant

Up front it is a true coilover; the rear keeps a divorced layout, with the spring and shock mounted separately like the factory setup. Damper bodies are 50mm front and 46mm rear. It comes with 14 kg/mm (about 784 lb/in) springs up front and 9.5 kg/mm (about 532 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.

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
  • Ride height lowers roughly 1 to 2.5 inches below stock (SF Racing's figure) without giving up 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
  • Zinc-plated shock bodies for rust protection
  • SAE9254 cold-wound springs
  • NOK seals and Italian IP damping oil
  • Built-in dust boots and bump stops

Who it suits

A good fit if the car is driven on the street most of the time and you want a lower stance with better body control.

Before you order: Audi A6 Avant fitment and setup

If you want more control over stance and handling than lowering springs give you on a Audi A6 Avant, a coilover kit like this SF Racing set is the usual next step.

  • Drivetrain: FWD. FWD and AWD versions of the same car often take different parts.
  • Factory adaptive dampers: if your car has electronic or adaptive suspension, check whether the listing covers it or needs a cancellation kit.

Plan the whole job

  • 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 A6 Avant coilovers

Will this fit my Audi A6 Avant?
It is listed for the 1997-2004 Audi A6 FWD Avant (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.
