BC Racing ZX Series - Audi S1 8X AWD (2015-2018)

BC Racing ZX Series Coilovers – Audi S1 8X AWD (2015–2018)

Take the suspension setup of your Audi S1 8X further with the BC Racing ZX Series coilover kit, designed for drivers wanting a more focused setup for fast-road, track day and motorsport use.

The ZX Series combines BC Racing’s adjustable monotube coilover design with a more performance-led specification, making it well suited to cars where sharper response, stronger chassis control and greater setup flexibility are a priority.

For the Audi S1 8X AWD, the kit is available with 9/6kg.mm or 9/8kg.mm spring-rate configurations.

Performance-Focused Coilover Design

The ZX Series is intended for drivers looking for a firmer and more track-focused setup than a conventional road-biased coilover package.

Its adjustable dampers allow the suspension to be fine-tuned to suit the vehicle, road conditions and intended use, while independent ride-height adjustment helps retain usable damper travel when lowering the car.

Key features:

• ZX Series monotube coilover design

• 30-way adjustable damping

• Independent ride-height adjustment

• Adjustable spring preload

• Performance-focused damping characteristics

• Improved body control under braking and cornering

• Sharper chassis and steering response

• Rebuildable design

• Replacement components available

• Custom specification options available

• Designed for the Audi S1 8X AWD

Spring Rate Options

Available spring-rate configurations include:

9/6kg.mm – recommended spring rate for a balance of comfort and performance

9/8kg.mm – firmer, more track-focused setup for increased rear support and chassis response

The 9/6kg.mm configuration provides a strong all-round performance setup, offering increased control over the standard suspension while retaining a more usable balance for fast-road driving.

The 9/8kg.mm option increases rear spring rate for drivers wanting a more focused chassis setup, particularly where sharper rotation, reduced rear body movement and stronger support during track use are priorities.

Adjustable Ride Height & Damping

Ride height can be adjusted independently of spring preload, allowing the vehicle to be lowered without unnecessarily reducing available damper travel.

The 30-way damping adjustment allows the suspension response to be tailored to suit road use, fast-road driving or more demanding circuit work.

Vehicle Fitment

Designed for:

• Audi S1 8X

• 2.0 TFSI Quattro / AWD

• 2015–2018

Product Image & Specification Note

Product images are for illustration purposes only and may not show the exact specification supplied for every vehicle application.

BC Racing kits can vary depending on vehicle, spring rate, top mount configuration and other specification options. If you have any specific requirements, such as upgraded or alternative top mounts, spring rates or ride-height preferences, please contact us before ordering so we can confirm the most suitable configuration for your setup.

Fast Road & Track Performance

The ZX Series is particularly well suited to more performance-focused Audi S1 builds where chassis control, steering response and adjustability are more important than outright comfort.

The 9/6kg.mm configuration provides the more balanced option for road and track use, while the 9/8kg.mm setup is better suited to drivers looking for a firmer and more responsive track-oriented chassis.

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.
