Fine Tuning Rear Roll Centre for the XB8

For drivers wanting to tune chassis behaviour, the XRAY 353185 Composite Bushings provide targeted adjustments for the XRAY XB8. Built to work with the XB8 Aluminum Rear Upright (#353366) and the complete XRAY XB8 Aluminum Rear Uprights kit (#350908), these bushings let you modify rear roll centre geometry with confidence.

Two Positions for Tailored Handling

The kit contains two moulded composite bushings that create two possible roll centre positions. By swapping the bushings you can change how the rear end reacts during corner entry and mid corner, adapting the car to different surfaces. Fit identical bushings to both sides to maintain steering balance and predictable response.
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 changing bushings affect tyre wear?

Adjusting roll centre changes load patterns through the rear tyres which can alter wear rates. Small changes can improve traction without dramatically increasing wear when set correctly.

Do these work with aluminium uprights only?

They are intended for use with the XRAY XB8 aluminium rear uprights, specifically #353366 and the set #350908, to ensure correct alignment and function.

How should I choose between the two settings?

Try the higher roll centre for more responsive rear grip on smoother tracks, and the lower setting for improved traction on bumpy or low grip surfaces. Make small changes and test lap times to find the best option.
