Control rear roll with the XRAY 343478 unit

The XRAY 343478 - Rear Anti-roll Bar 2.8mm for RX8E is intended to give RX8E chassis better rear stability by reducing unwanted body lean. The 2.8mm section is chosen to influence mid-range roll characteristics while preserving overall balance.

Geometry that simplifies setup

The profile of this anti-roll bar matches the updated bearing bushings so eccentric bushings are not needed in the fixed rear holders. This makes down-stop setup quicker and more repeatable at the track.

Practical for racing and testing

Drivers can use this bar when refining handling for heats or test sessions; it provides a durable, consistent option for tuning rear behaviour under 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.

How do I know if I need a different rear bar?

If the car feels loose in mid-corner or rolls excessively, trying a different rear bar stiffness is a logical next step to tune rear grip and transition.

Can worn bushings affect performance?

Yes, worn or loose bushings introduce play and inconsistent roll behaviour; replacing them keeps the anti-roll bar working as intended.

Is this bar suitable for practice sessions?

Absolutely, it is suitable for regular practice and race weekends and helps you establish a repeatable baseline for rear tuning.

Any tips for swapping bars trackside?

Keep notes of mounting position and bushing condition, change one variable at a time, and make short test runs to evaluate the effect before committing to further changes.
