ST XTA Plus 3 Coilovers - Toyota GR Yaris - 1820256823 / 1820256827

ST XTA Plus 3 Coilover Suspension – Toyota GR Yaris

Upgrade the Toyota GR Yaris with the ST XTA Plus 3 Coilover Suspension Kit, the most adjustable coilover system in the ST Suspension range.

Developed using KW suspension technology, the XTA Plus 3 combines adjustable ride height, independent 3-way damping adjustment and aluminium Unibal top mounts to give significantly greater control over the way the GR Yaris behaves on road and track.

Available part numbers:

• 1820256823 – Toyota GR Yaris Gen 1, 2020–2024

• 1820256827 – Toyota GR Yaris Gen 2, 2024 onwards

3-Way Adjustable Damping

The ST XTA Plus 3 allows separate adjustment of rebound, low-speed compression and high-speed compression damping.

This gives you much more control over the chassis than a conventional single-adjustment coilover, allowing the suspension to be tuned around different tyres, alignment settings, driving conditions and intended use.

Adjustment includes:

• 16-stage rebound adjustment

• 24-stage low-speed compression adjustment

• 24-stage high-speed compression adjustment

Low-speed compression primarily influences chassis movements such as body roll, steering response, braking and acceleration behaviour, while high-speed compression has a greater influence over sharper suspension inputs such as bumps, kerbs and road imperfections.

Adjustable Ride Height

Both GR Yaris applications offer approximately:

• Front: 25–45mm lowering

• Rear: 25–45mm lowering

The threaded adjustment system allows the ride height to be tailored within the vehicle-specific approved range, making it possible to optimise both stance and chassis setup.

Adjustable Unibal Top Mounts

The XTA Plus 3 includes aluminium Unibal top mounts on the front axle, allowing additional suspension geometry adjustment compared with the factory setup.

Front camber can be fine-tuned after installation, helping optimise tyre contact, steering response and front-end grip.

This is particularly useful for fast-road and track-focused GR Yaris builds where alignment plays a significant role in overall handling balance.

Galvanised Steel Construction

The coilover struts use galvanised steel housings with additional corrosion protection, designed to provide durability during year-round road use.

ST also uses corrosion-resistant spring adjustment components, integrated dust protection and robust sealing to help maintain long-term adjustment and reliability.

Developed for the GR Yaris

The GR Yaris already has a highly capable chassis, making the XTA Plus 3 particularly suited to drivers who want to fine-tune rather than simply lower the car.

The combination of adjustable damping, geometry adjustment and ride height control allows the suspension to be tailored around different tyre compounds, wheel setups, alignment specifications and driving styles.

This makes it an excellent option for GR Yaris builds ranging from aggressive fast-road setups through to regular track use.

Product Image & Specification Note

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

ST Suspension kits can vary depending on vehicle generation, model year and specification. If you are unsure whether 1820256823 or 1820256827 is correct for your GR Yaris, please contact us before ordering so we can confirm compatibility.

Professional Installation Recommended

Professional installation is recommended.

A full four-wheel alignment should also be carried out once the suspension has been installed and the final ride height has been set.

For performance-focused setups, the adjustable front top mounts can then be used as part of a more detailed geometry setup to optimise camber, tyre utilisation and front-end response.
