Listed for: 2005-2008 Audi S4 Quattro AWD (B7/8H)AWDFitment notes & questions

This is SF Racing's track-oriented coilover kit for the 2005-2008 Audi S4 Quattro (B7/8H): 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.

2005-2008 Audi S4 Quattro setup details

The front uses true coilovers, while the rear stays divorced (separate spring and shock), matching how the car is built from the factory. Damper bodies are 50mm front and 46mm rear. It comes with 14 kg/mm (about 784 lb/in) springs up front and 8 kg/mm (about 448 lb/in) at the rear. Damping is 1-way: a single knob with 32 settings changes rebound and compression together, which keeps tuning quick.

Key features

  • Monotube dampers, which shed heat well and hold their damping under hard use
  • 32-level damping adjustment, rebound and compression combined on one adjuster
  • 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
  • Zinc-plated shock bodies for rust protection
  • Cold-wound SAE9254 spring steel
  • NOK seals and Italian IP damping oil (20W)

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.

Before you order: Audi S4 Quattro fitment and setup

If you want more control over stance and handling than lowering springs give you on a Audi S4 Quattro, a coilover kit like this SF Racing set is the usual next step.

Fitment notes

  • Listed for: 2005-2008 Audi S4 Quattro AWD (B7/8H).
  • Model years: 2005-2008. Check your car's year falls inside this range.
  • Chassis code B7/8H: parts for other chassis codes of the same model usually won't fit.
  • 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.

Not sure it fits? Message us your car's details and we'll double-check fitment with the supplier before you buy.

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 S4 Quattro coilovers

Will this fit my Audi S4 Quattro?
It is listed for the 2005-2008 Audi S4 Quattro AWD (B7/8H). 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.
