Tune Roll-Centre for Balanced Corner Work

The XRAY 323043 Aluminum Rear Roll-Center Holder upgrades the XB2 series with a robust 7075 T6 construction. Its three-position layout makes it easy to change roll-centre characteristics to suit different tracks and driving styles.

Why Use 7075 T6 on Racing Parts

7075 T6 aluminum provides a reliable mix of stiffness and low weight, helping components resist flex under load. That stability translates into crisper inputs and steadier rear-end behaviour during aggressive laps.

Designed for XB2 2020 Carpet and Dirt Specs

Made to fit the XB2 2020 Carpet and Dirt Specs without modification, the holder allows quick roll-centre swaps so you can adapt between loose dirt and grippy carpet sessions.

Specifications

  • Material: 7075 T6 Aluminum
  • Compatibility: XB2 2020 Carpet / Dirt Specs
  • Adjustment Positions: 3

A straightforward upgrade for drivers who want repeatable roll-centre options to refine XB2 balance and traction.
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 keep my existing shocks when fitting this part?

Yes, the XRAY 323043 fits with standard XB2 shock setups. You may need minor valving or spring changes after altering roll-centre to fine-tune balance.

Does this add noticeable weight to the rear?

The holder adds minimal weight relative to plastic parts while providing greater rigidity. The weight tradeoff is small compared with the handling benefits on track.

How should I log changes when testing positions?

Record lap times and driver notes for each position, and make one change at a time. Track surface and tyre wear should be noted to compare results accurately.
