Tune Rear Toe with the XRAY 300902 ARS for the T4'20

The XRAY 300902 - T4'20 ARS Active Rear Suspension Set is a focused upgrade intended to refine rear dynamics of the T4'20 chassis. The package contains precision suspension arms, aluminium C-hubs, sturdy steering blocks and ARS linkages that alter rear toe-in as the chassis rolls to improve control.

Precise Shim-Based Adjustment

The ARS design offers stepwise control of rear geometry via shims. Modifying the shim stack between the steering block and holder changes toe-in behaviour under roll, so you can tune mid-corner rotation and exit traction to match grip levels.

Purpose-Built for the T4'20 Chassis

Produced to fit the T4'20 layout, the components install cleanly alongside stock parts. Aluminium C-hubs boost rigidity while reinforced steering blocks are built to withstand racing stresses, giving repeatable performance.

Specifications

  • Compatibility: T4'20 Chassis

The XRAY T4'20 ARS Active Rear Suspension Set suits drivers who want targeted rear tuning. Its adjustable setup helps achieve a balanced handling package across different circuits.
Remark :
Due to limited stock availability, please notice that some XRAY items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

How do I assess the effect of ARS changes on lap time?

Run controlled test laps with a consistent fuel or battery state and tyre condition. Change a single shim at a time and compare lap consistency and corner exit speed to evaluate the effect.

Is any special tooling required to fit the XRAY 300902 set?

Basic hand tools used for standard chassis work are sufficient. Precision screwdrivers, hex drivers and a small set of shims or feeler gauges will help you set the ARS stack accurately.

Will the ARS kit affect tyre wear?

Depending on your settings, changes in toe-in under roll can influence rear tyre scrub and wear patterns. Monitor tyre condition after setup changes and adjust shims to balance performance and longevity.
