Rear ballast upgrade for XRAY XB4 chassis

The XRAY 361191 Brass Rear Chassis Brace Weight is a solid brass upgrade tailored for the XB4 platform. At 40g it locates in the lower composite brace and fixes to the chassis to bias mass to the rear, which lowers the effective centre of gravity and aids rotation during cornering.

CNC accuracy for repeatable performance

Made by CNC machining to tight tolerances, the weight provides a reliable fit and consistent behaviour across race days. Its rear placement influences chassis flex and traction balance, helping fine-tune handling for a variety of track conditions and driving styles.

Specifications

  • Material: Brass
  • Weight: 40g
  • Compatibility: XRAY XB4 Series (2016-2021)
  • Machining: CNC-Machined

A handy upgrade for racers seeking a simple, effective way to alter rear-end behaviour and cornering balance.
Remark :

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 make the car oversteer more?

Adding rear mass tends to encourage rotation which can feel like more oversteer if not balanced with shock and anti-roll settings. Use it to fine tune rotation rather than as a sole fix for handling problems.

Is the fitment durable under race conditions?

Yes, the CNC finish and solid brass construction provide durable fitment. Check mounting hardware periodically and replace any worn fasteners to maintain secure attachment.

Should I retune my dampers after installing it?

It is advisable to revisit damper and shock settings after adding the weight, as the change in mass distribution can alter body motion and rebound characteristics. Small adjustments can restore balance quickly.
