Product Details

BC Racing ZX Series Coilovers for the 2005-2013 Audi A3 (MK5) bring the same three-axis adjustability as the race-spec ZR Series with valving tuned for drivers who split time between street and track. Every kit is extensively tested on the MK5 chassis and refined until it balances ride quality with performance — the reason A3 coilovers from BC Racing are the best-selling adjustable kits in their segment worldwide.

ZX Series kits share the three-axis damper architecture of the race-spec ZR Series, tuned out of the box for drivers who want race-grade adjustability without the ride harshness on the commute home. The off-the-shelf setup from BC Racing is deliberately balanced — spring rates and valving chosen so the kit feels comfortable day-to-day without giving up performance when you push it. Drivers who want a different recipe can spec Swift Springs, custom spring rates, or fully custom valving at checkout; BC will tune the dampers to match, which is a depth of customization most brands only offer on their top-tier kits.

BC Racing has been manufacturing adjustable coilovers since 2004 and is one of the most popular coilover brands in the automotive tuning industry for a reason: competitive pricing, deep customization, proven reliability, and a fully rebuildable damper design that lasts years instead of seasons. These A3 coilovers arrive tuned for the MK5 chassis and ready to bolt in — no break-in period, no guessing at setup. Every kit ships with a 2-year manufacturer warranty, lifetime access to BC service parts (pistons, seals, shafts — no unit replacement required when it's time for a rebuild), and in-house tech support from both BC Racing and the Springrates team.

Reviews / Q&A

FAQs

Please read our FAQs page to find out more.

How much will BC Coilovers lower my car?

On average, Standard Drop allows about 1-2 inches of drop range below factory ride height. Extreme Low allows about 2-3 inches of drop.

Can BC Coilovers achieve factory ride height?

No. In most cases, factory ride height cannot be achieved.

What is a custom build vs off-the-shelf kit?

The stock level displayed on our website reflects the availability of standard “off-the-shelf” kits, unless noted otherwise in the product description. Selecting any custom options—such as Extreme Low, custom spring rates, Swift Spring upgrades, or top mount changes—will result in a custom-built kit. Please note: all series except the BR Series are built to order, with the exception of select popular DS Series kits that may be in stock. Also, some popular Extreme Low kits are in stock as well. To identify these, look for "Extreme Low" in the product title.

Will the struts be valved correctly?

Yes! The shocks and/or struts are always valved to match the spring rates you choose during a custom build. There is no additional cost.

Can they be rebuilt?

Yes, all BC Racing Coilovers can be rebuilt by purchasing individual replacement parts. For example, if a strut leaks, you can simply replace the shock cartridge.

Is there rush shipping available?

Rush shipping is not offered, but all in-stock kits ship very fast— most by the next day.

Customizing the coilovers in any way will delay the shipment by a few weeks on average.
