Tune Rear Geometry for Carpet Racing with XRAY 323040

The XRAY 323040 Composite Rear Roll-Center Holder - Carpet Edition is a purpose-built component that helps you dial in handling on indoor carpet tracks. The precision-molded composite offers a controlled flex-to-strength ratio, giving consistent behaviour in low, medium and high-traction settings. Whether you are trimming lap times at the track or refining a race setup, this holder provides dependable adjustment.

Improved Traction and Corner Stability

Made for carpet surfaces, the XRAY 323040 holder enhances rear traction and keeps the chassis stable through fast corners. The composite construction is durable enough for regular club racing while still allowing tuning changes that affect handling predictably.

Setup Benefits for Competitive Drivers

Adjusting the roll center with this holder helps reduce inside rear lift and can improve corner entry and mid-corner speed. It is a useful tuning item for drivers chasing consistent lap times and better rotation on carpet layouts.
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.

What XRAY kits work with this roll-center holder?

This part is made for XRAY models set up for carpet racing. It will fit other cars only if their rear bulkhead and suspension geometry match the XRAY mounting points.

Will it change how the car feels on high-traction tracks?

Yes. Changing roll center alters weight transfer and can make the rear more planted in high-traction conditions, but you may need to retune shock and anti-roll settings to balance the car.

Any tips for installation and setup?

Check alignment and mounting hardware for proper fit, then test one change at a time. Note how corner entry and mid-corner behavior respond before making further adjustments.
