Sharpen Rear-End Control with XRAY 303353

The XRAY 303353 hard composite right rear upright is engineered to tighten the handling of your racer. The built-in 1° outboard toe-in improves turn-in and rotation, while the hard composite construction is targeted at foam tyre applications and also works with rubber tyres.

Track-Proven Strength and Setup Options

This upright offers two distinct roll centre positions on the top for tuning suspension behaviour to suit cornering demands. It is compatible with compact 5x10 ball bearings to reduce unsprung mass and maintain nimble response. The stiff composite helps preserve suspension geometry during heavy use.

Pairing and Practical Setup Advice

Use this right upright together with the left-side counterpart model 303363 to achieve balanced handling. Small changes to roll centre and toe will adapt XRAY 303353 to different tyre compounds and track grip.
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 I run this upright on high-grip foam tyres?

Yes. The hard composite and 1° outboard toe-in are well suited to high-grip foam tyres to help the car rotate cleanly into corners.

Will the material stand up to rough handling?

The hard composite is tough and maintains geometry after impacts, though very heavy crashes can still damage parts. Inspect for cracks after incidents.

How much setup change does the toe-in add?

The fixed 1° outboard toe-in gives a predictable rotation bias. Tune other suspension parameters like roll centre and shock settings to balance the effect.

Are there recommended bearings to use?

Use high-quality sealed 5x10 bearings for longevity and smooth operation, especially in dusty or damp conditions.

Should I change camber when fitting this upright?

Minor camber adjustments may be beneficial after fitting to fine-tune tyre contact patch, but start from your baseline and make small incremental changes.
