Dial Rear Geometry with the XRAY 300902 ARS for T4'20

The XRAY 300902 - T4'20 ARS Active Rear Suspension Set is an engineered upgrade that refines how the rear of the T4'20 reacts during driving. The set contains precision suspension arms, aluminium C-hubs, robust steering blocks and ARS linkages that actively modify toe-in as the chassis rolls.

Adjustable Toe for Better Turn-In

The ARS solution gives you control over rear suspension behaviour via shim tuning. Adjust the shim thickness between the steering block and holder to change toe-in under roll, helping to balance turn-in and mid-corner rotation based on track grip and tyre selection.

Matched to the T4'20 Chassis Layout

Built with the T4'20 architecture in mind, the components fit without compromise. Quality materials such as aluminium in the C-hubs improve rigidity while the strengthened steering blocks stand up to race use, maintaining consistent feel.

Specifications

  • Compatibility: T4'20 Chassis

For drivers seeking a more tunable rear end, the XRAY T4'20 ARS Active Rear Suspension Set provides targeted adjustments that help customise balance and rotation for 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.

Will the ARS set change my car's balance a lot?

Changes are incremental and focused on rear toe behaviour during roll. Small shim adjustments can noticeably affect mid-corner rotation and exit traction without overhauling the whole setup.

What should I try first when setting up the ARS?

Start with a neutral shim stack and test a few laps, then add or remove thin shims to see how toe-in under roll changes handling. Make single-step changes to isolate effects.

Are spare parts available for the XRAY 300902 kit?

Replacement arms, linkages and C-hubs are commonly available from XRAY parts lists. Check with your supplier for compatible spares to match the 300902 set.
