Tune Cornering with XRAY 303364 Composite Rear Upright

The XRAY 303364 Composite Rear Upright is crafted for racers aiming to sharpen handling on high-traction surfaces. Featuring an integrated 0 deg outboard toe, this composite upright helps preserve suspension geometry under load and its one-hole layout promotes faster, more predictable cornering on sweeping circuits.

Designed for Foam Tires and Aggressive Tracks

Made from hard composite material marked with "H" for added stiffness, this upright is optimised for foam-tire competition while remaining usable with rubber tyres. The design reduces unsprung mass and includes compact 5x10x4 bearings to help smooth suspension response and improve overall stability.

Adjust Roll Centre Easily

Fine tuning is straightforward: add shims between the upright and the turnbuckle ball joint to alter roll centre height. This tuneable feature lets racers adapt handling to changing track grip and driving style.
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.

Can the XRAY 303364 be mounted on either side of the car?

Yes. The XRAY 303364 fits both left and right positions and installs with standard mounting hardware for straightforward replacement.

Is this upright suitable for rubber tyres as well as foam?

While tuned for foam tyres, the hard composite construction also works well with rubber tyres, giving a versatile option across surfaces.

How do I change roll centre with this upright?

Insert shims between the upright and the turnbuckle ball joint to raise or lower the roll centre. Small adjustments can noticeably affect turn-in and mid-corner balance.
