Rear mass tuning for XRAY XB4 with XRAY 361191

The XRAY 361191 Brass Rear Chassis Brace Weight is a machined brass accessory intended to sharpen your XRAY XB4's handling. Weighing 40g, it installs into the lower composite brace to move ballast toward the rear of the car, lowering roll centre effects and improving yaw response for cleaner exits.

Tune rotation and flex response

Manufactured by CNC for tight tolerances, the weight fits precisely and provides consistent performance lap after lap. Its location allows nuanced adjustments to chassis flex and rear traction, making it useful across different surfaces from low-grip carpet to packed dirt when seeking more rotation.

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.

Will this weight affect jump landings?

Shifting mass rearward can stabilise rear-end landings and reduce forward pitching, but suspension setup and damping also play a large role. Test progressively to find the right balance for your track.

Can I tune handling without changing springs?

Yes, adding this rear weight alters balance and rotation without swapping springs. Use it alongside small shock and roll bar adjustments to fine tune handling before changing major components.

Is the brass finish likely to corrode?

Brass is relatively corrosion resistant, but keep the part dry and clean after running in wet or salty conditions to maintain appearance and fit.
