Improve Corner Rotation with XRAY 303353 Upright

The XRAY 303353 hard composite right rear upright is a precision part that sharpens handling for road racing rigs. Its built-in 1° outboard toe-in helps the car initiate and sustain rotation through turns, and the stiff composite is optimised for foam tire use while remaining effective with rubber tires.

Built for Strength and Track Consistency

This upright provides two selectable top roll centre positions for suspension tuning to match track grip and cornering style. It accepts compact 5x10 ball bearings to reduce unsprung mass and keep steering response crisp. The hard composite construction holds geometry under load, giving reliable service on race day.

Setup Notes and Pairing

For balanced handling, fit the matching left-side upright model 303363 with this right rear unit. Small setup changes to roll centre and toe can adapt the XRAY 303353 to different tire compounds and track surfaces.
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 this upright work on rubber tires as well as foam?

Yes. Although the part is aimed at foam tire setups, the hard composite shape and toe-in are compatible with rubber tires when you tune roll centre and toe settings.

How do the two roll centre positions affect handling?

Higher roll centre tends to make the car more responsive and reduce body roll, while lower roll centre increases mechanical grip. Use the positions to fine-tune rotation and stability for each track.

What bearings should I use with this upright?

This upright is designed for compact 5x10 ball bearings. Choose sealed race bearings for durability and smoother response under load.

Any tips for setup after installation?

Start with the stock roll centre and toe settings, then raise or lower roll centre and test small toe changes to dial in rotation without oversteer. Check bearing preload after fitting.
