XRAY 351182 Brass Rear Upright Weight Pack for XB Classic Models  [XR-351182]

Rear Upright Brass Weight Upgrade for Classic XB Models with XRAY 351182

The 351182 Brass Rear Upright Weight Set gives owners of older XRAY XB Series cars a compact way to improve stability by adding 15g of brass mass. Fitted beneath the rear upright, the weight helps lower the centre of gravity on vintage chassis and can make the car feel more composed during competitive or club runs.

Why Add Weight to the Rear Upright

Adding brass directly under the rear upright influences roll and yaw behaviour, often reducing sudden weight transfer that leads to instability. The change promotes steadier cornering and helps maintain traction through mid-corner sections without altering primary suspension geometry.

Compatibility, Installation and Practical Tips

This weight set is manufactured for older XB Series rear uprights and mounts cleanly to the existing points. Installation is straightforward and reversible, making it easy to test on-track before committing to a permanent setup change.
