Audi A5, S5 and RS5 Coilovers

We carry forty-nine sets of Audi A5, S5 and RS5 coilovers for 2007 to 2023 cars: coupe, Sportback and convertible. On the B9 A5, the front strut size and electronic damping decide which BC and KW kit fits. KW also has different kits for each body style.

Not sure about strut size or damping? Call 1-800-460-9106 with your VIN and we will check.

Animated illustration. It shows where coilovers sit on a car, not your exact kit. Depending on the car and the kit, coilovers can lean forward or back or stand straight up, and some cars use a separate spring and shock in the rear. Your ride height depends on the kit and how it is set up.

B8 or B9, A5 or RS5

Strut, damping and body: what to check on an A5

These three things decide which Audi A5 coilover kit to look at.

Front strut size

Most BC and KW B9 kit names give a 48.5mm, 50mm or 53mm strut size.

Electronic damping

BC, KW and Öhlins have kits for it, or parts that cancel it.

Body

KW has separate B9 coupe, Sportback and convertible kits.

BR, DS, ER and ZX on an A5

Here is what each BC series does on the A5.

BR and DS

BC Racing BR coilovers set compression and rebound together on one 30-click knob. DS adds a firmer, digressive piston.

ER

ER is an upright shock with an external oil reservoir, and compression and rebound adjust separately.

ZX

Before you buy: what A5 owners run into

Here is what A5 owners report most often in forums, recalls and service bulletins, and what each one means for your coilover suspension.

Worn front upper control arm bushings
A5 and S5 (B8), 2008 to 2017; Audi bulletin covers 2002 to 2016 models

A5 owners on AudiWorld say the front upper control arm bushings are a known issue and can tear early, with noise as the warning sign. Audi bulletin 2016453 covers clacking from torn front upper link bushings. Worn arm bushings let the alignment move, so the car can still clunk or wander after new coilovers.

Before you install: Inspect the four front upper links during the install, replace torn ones as a set with new stretch bolts, and align afterward.

RS5 Dynamic Ride Control lines and leaks
RS5 (B8), 2010 to 2015, with optional DRC

Audi's optional Dynamic Ride Control links opposite shocks through hydraulic lines and a central valve. One RS5 owner traced a rear knock to pressure lost through a pinhole in a DRC hose. An RS4 owner warns some kits lack caps for the open lines. Coilovers on a DRC car mean opening a pressurized hydraulic system.

Before you install: Confirm DRC from the VIN, plan how the lines will be drained and capped, and ask us whether your kit includes the caps.

No front camber adjustment without new arms
A5, S5 and RS5 (B8 and B8.5), 2008 to 2017

On Audizine, a parts maker explains the B8 front end has four control arms and no camber plate, so camber changes need adjustable upper arms. A B8.5 S4 owner on coilovers reports about -1.9 degrees front camber, and an installer says worn bushings add more. Bigger drops add front camber the stock arms cannot remove.

Before you install: For more than a mild drop, budget for adjustable front upper arms and replace worn arm bushings before the alignment.

The A5 story

Debut in Geneva, 2007

At the A5 and S5 debut in Geneva in 2007, AudiWorld quoted VW Group chief designer Walter de Silva: "The Audi A5 is the most beautiful car I have ever designed."

  1. 2007
    What de Silva said"It is a masterpiece."

Questions about strut size, damping and the RS5

How do I know my B9 front strut size?

BC and KW name their B9 kits by front strut size: BC by 48.5mm or 53mm, KW by 48.5mm or 50mm. Read us the VIN and we will help you confirm it before ordering.

Which Audi A5 coilovers fit a car with electronic damping?

BC has "With EDC" kits for the B9, KW has kits for cars with electronic damping that include an ESC module (B9) or a magnetic ride cancellation unit (B8), and Öhlins has DCC cancellation kits for the B8. Bilstein's A5 kits are for cars without electronic suspension.

Coupe, Sportback or convertible: does it matter?

For KW on the B9, yes: each body has its own kits. Bilstein and Ksport also have separate B8 cabriolet kits.

What do you have for the RS5?

KW has B8 and B9 RS5 kits, Bilstein has B9 RS5 EVO T1 kits, and Öhlins has Road & Track kits for both generations. Solo-Werks' B8 kit, listed with the A5 and S5, is named A5 Quattro/S5/RS5 (Coupe/Convertible). BC has none.

Which of BC's series can I get on an A5?

BC has four series in total. The B9 kits without EDC come in all four; the With EDC kits and the shared B8 kits come in BR or DS.

What does BC's warranty cover?

BC Racing North America currently lists a two-year limited warranty on full kit orders, subject to its warranty terms. KW, Öhlins, Bilstein, Solo-Werks and Ksport publish their own.
