Engineered upright for improved turn control

The XRAY 303361 Composite Left Rear Upright is aimed at drivers wanting steadier rear-end behaviour, offering a 1° outboard toe-in to reduce unwanted suspension movement during impacts. The component helps maintain consistent line through fast sections.

Made for rubber tyre competition

This upright is manufactured in medium rigidity, marked "M", and is optimised for rubber tyre use. It features two selectable top roll centre settings and accepts 5x10 ball bearings to cut unsprung weight and sharpen handling.

Fitment info and adaptability

Intended to be used with the corresponding right rear upright 303351, this part is compatible with both rubber and foam tyre setups and adapts easily to a range of race conditions.
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 accept foam tyres?

Yes. The XRAY 303361 supports foam tyre use as well as rubber, allowing you to run either compound depending on the event or track.

What bearing size is specified?

It is designed for compact 5x10 ball bearings which help reduce rotating and unsprung mass for crisper rear handling.

How does the 1 degree outboard toe-in affect handling?

The built-in 1 degree outboard toe-in promotes more stable cornering by slightly biasing rear toe under load, which can improve mid-corner balance and predictability.
