Rear ballast solution for XRAY XB4 featuring XRAY 361191

The XRAY 361191 Brass Rear Chassis Brace Weight is a precisely machined brass upgrade built for XB4 racers who want more rear bias. At 40g it fits into the lower composite brace and couples to the chassis to pull mass rearwards, which helps lower the centre of gravity and refines turn-in response.

Precision fit for consistent handling

CNC-machined construction ensures repeatable fitment and consistent on-track behaviour. By changing the mass distribution the part aids in adjusting chassis flex and rear grip, making it a useful tool when tuning for different track surfaces or tyre compounds.

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 use this weight when setting up for carpet racing?

On carpet, the extra rear mass can help increase rotation and reduce understeer. Start with small incremental changes and re-evaluate handling after a few laps to avoid overcompensating.

Will the weight affect tyre wear?

Shifting weight rearward can change load distribution and may alter rear tyre wear patterns. Monitor wear and adjust camber or toe as needed to maintain even wear.

Can I combine this with other weights?

Yes, the brass weight is one part of a broader ballast strategy. Combine it carefully with other weights to tune balance, but make changes one at a time to isolate effects.
