Rear-End Tuning with the XRAY 303721 Brass Holder

The XRAY 303721 Brass Rear Lower Suspension Holder is crafted to add deliberate weight to the rear bulkhead area, helping your model rotate more predictably. It is a practical upgrade for racers dialing in their setup.

How the Added Mass Affects Handling

Brass offers significantly more weight than aluminium parts, letting you bring the car up to minimum weight while preserving chassis compliance. A lower centre of gravity and balanced left-right mass improve turn-in and mid-corner stability.

Where to Use It Depending on Grip

Mounted at the front it reduces traction roll on sticky surfaces, while rear mounting encourages rotation and improved steering feel on medium-grip tracks. Swap positions to quickly evaluate what your track needs.
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.

Does the brass holder affect corner entry?

Yes, by shifting mass lower and toward the rear it can change how the car turns into corners, often smoothing entry and improving balance on throttle application.

Is it compatible with other XRAY parts?

It pairs with standard XRAY rear bulkhead assemblies. Confirm your chassis layout and mounting pattern to ensure fitment.

How should I test it on track?

Try one brass holder at the rear, run a few laps to assess rotation and steering, then compare to your baseline setup. Record changes to springs or swaybars if needed.
