XRAY 309828 - X4F Front Balancing Weight Set, Stainless Steel bumper and left/right weights (30g+40g+40g)  [XR-309828]

Front balancing weights for X4F

This front balancing weight set is an RC-scale tuning accessory designed to alter front-end mass and handling on the X4F platform. The kit contains dedicated bumper and side weights that locate close to the front drivetrain and inside the front bumper to change how weight transfers during acceleration and braking. The components are CNC-machined from stainless steel and laser engraved for straightforward identification and repeatable mass accuracy.

On-track use is focused on tuning front grip and rotation. By adding fixed mass ahead and beside the front drivetrain, the set helps reduce abrupt front weight transfer, which can lead to more predictable turn-in and steadier behavior under throttle and braking. The design supports incremental tuning: teams can test the included combination before moving to different mass values or mounting strategies.

The kit emphasizes fit and repeatability rather than being a tool for radical setup changes; it is intended for drivers who need fine control over front-end balance without modifying suspension geometry.

This XRAY front balancing weight set provides a durable, repeatable option for front-end tuning on X4F cars, allowing measured changes to rotation and corner stability without altering suspension components.
