Rear upright built for consistent cornering

The XRAY 303361 Composite Left Rear Upright fits racers who want predictable rear behaviour, offering a 1° outboard toe-in to keep suspension geometry stable during heavy loads and impacts. The clean profile helps maintain handling feel through long corners.

Optimised for rubber tyre events

Produced in medium stiffness "M", this upright is tailored to rubber tyre competition. It provides two top roll centre settings and takes compact 5x10 ball bearings to reduce unsprung mass and improve rear traction response.

Compatibility and setup flexibility

This left-side part pairs with right-side upright 303351 and is suitable for both rubber and foam tyre setups, making it flexible for different track surfaces and setup philosophies.
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 use this upright with foam tyres?

Yes. The XRAY 303361 works with both foam and rubber tyres, so you can adapt the car to changing grip or class rules.

Does it require large bearings?

No, it is designed for small 5x10 ball bearings which help keep the rear light and responsive.

How do I experiment with roll centre settings?

Swap between the two top positions to see how the rear grip and turn-in change; small increments of roll centre change often give noticeable handling differences.
