Race-oriented aluminium caster bushings for XRAY X1 setups

The XRAY 372327 X1 Aluminum Caster Bushing Set provides a controlled way to adjust caster within a 6 to 9 degree window to suit different circuits and driving styles. Manufactured from aluminium for predictable performance, these bushings help maintain steering geometry under load for more stable handling.

Why upgrade to aluminium bushings

Aluminium offers a firmer, more dimensionally stable option than some plastics, reducing unwanted flex at the steering pivot and keeping settings repeatable. The XRAY 372327 kit includes three inserts so you can test and apply your preferred caster choice.

Setup strategy for consistent lap times

Use the 6 to 9 degree steps to tune front-end behaviour; small changes can have noticeable effects on turn-in and self-centre action. Combine caster adjustments with shock and tyre setup to achieve consistent lap times.
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.

Do these bushings require additional spacers?

Most installations use the stock spacer arrangement, but verify clearance and kingpin alignment after fitting the XRAY 372327 inserts to ensure correct steering geometry.

Can the bushings be used for both practice and race days?

Yes, these aluminium bushings are suitable for testing in practice and for race use, offering consistent behaviour so you can rely on setup changes when conditions vary.

How do I choose between 6, 7, 8 or 9 degrees?

Start with a middle value and adjust based on understeer or oversteer tendencies. Higher caster often improves straight line stability, while lower caster may help quicker turn-in.
