BC Racing ZX Series Coilovers – Audi A3 / S3 8V Hatchback (2013–2020) 54.5mm
Upgrade the suspension of your Audi A3 or S3 8V Hatchback with the BC Racing ZX Series coilover kit, designed for drivers wanting a more performance-focused setup for fast-road, track day and motorsport use.
This application is specifically for vehicles using the 54.5mm front strut diameter, so the existing suspension should be checked before ordering to confirm compatibility.
The ZX Series combines a monotube damper design with 30-way adjustable damping and independent ride-height adjustment, giving you the ability to fine-tune the suspension around both road use and more demanding performance driving.
Performance-Focused Coilover Design
The BC Racing ZX Series is intended for drivers looking for increased chassis control, sharper response and greater setup flexibility than a more road-biased suspension package.
Its adjustable monotube dampers help improve body control under braking, acceleration and cornering, while still allowing the setup to be softened when required for road use.

ZX Series monotube coilover design

Designed for Audi A3 / S3 8V Hatchback models with 54.5mm front struts
Spring Rate
This kit is supplied with:
6/6kg.mm – recommended spring rate for a balance of comfort and performance
The 6kg.mm front and 6kg.mm rear spring-rate configuration provides a balanced setup for fast-road and track use, offering improved support and control without moving to an excessively stiff or uncompromising suspension setup.
Combined with the ZX Series dampers, this makes the kit well suited to drivers looking for a more focused chassis while retaining everyday usability.
Adjustable Ride Height & Damping
Ride height can be adjusted independently of spring preload, helping retain usable damper travel when lowering the vehicle.
The 30-way damping adjustment allows the suspension response to be tailored to suit road conditions, driver preference and intended use, from fast-road driving through to more demanding circuit work.

Fast Road & Track Performance
The ZX Series is particularly well suited to drivers wanting a more performance-led setup than a conventional road-focused coilover kit.

Professional Installation Recommended
Professional installation is recommended.
A full four-wheel alignment should also be carried out after installation and once the final ride height has been set to ensure correct geometry, tyre wear and handling characteristics.
