Listed for: 2012-2015 Audi RS 4 Quattro AWD (B8/8K)AWDFitment notes & questions

Built for daily-driven cars, this SF Racing Sport kit replaces the factory struts and springs on the 2012-2015 Audi RS 4 Quattro (B8/8K) with height-adjustable coilovers and single-knob damping adjustment. This version is listed for AWD models.

How this kit is set up for the 2012-2015 Audi RS 4 Quattro

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 10 kg/mm (about 560 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.

Features

  • Monotube damper design for better heat control and fewer leaks
  • 32 damping settings on a single knob that sets rebound and compression together
  • 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
  • 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

Who it suits

Ideal for street cars that need a sensible drop and some tuning range, without going to track-level stiffness.

About this coilover kit for the Audi RS 4 Quattro

Coilovers combine the spring and damper in one adjustable unit. That lets you choose your ride height on the Audi RS 4 Quattro and, on kits with damping adjustment, tune how firm it feels.

Fitment notes

  • Listed for: 2012-2015 Audi RS 4 Quattro AWD (B8/8K).
  • Model years: 2012-2015. Check your car's year falls inside this range.
  • Chassis code B8/8K: 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 RS 4 Quattro coilovers

Will this fit my Audi RS 4 Quattro?
It is listed for the 2012-2015 Audi RS 4 Quattro AWD (B8/8K). 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.
