The Serpent 401993 25 gram bumper weight provides a straightforward way to balance the Medius X20M FWD. It shifts weight forward to improve front-end contact and make steering more predictable on entry and mid-corner.
By adding this front mass the centre of gravity moves slightly forward, which helps lower roll and reduces the tendency to push wide. This is particularly useful on circuits where maintaining front bite is key.
The design integrates with the X20M FWD chassis without major changes, letting you test weight adjustments quickly during setup sessions.
A compact upgrade for drivers chasing cleaner turn-in and steadier high-speed behaviour.
