Ultra Racing rear lower chassis brace for BMW X3 F25/X4 F26

The vehicle chassis is the part subjected to the greatest loads while driving. This is particularly evident due to the transfer of the body’s weight during fast cornering, heavy braking or intensive acceleration.

In some cases, weight transfer when cornering can cause one side of the vehicle to be subjected to up to three times more force than the other. This can result in significant chassis flex, body deformation and loss of tyre grip.

Chassis deformation and flexing when cornering can cause undesirable driving characteristics such as understeer and oversteer.

This rear lower brace is designed to reduce such chassis flex and improve body rigidity during dynamic driving.

• Design: rear lower chassis brace
• Number of mounting points: 2

Suitable for: BMW X3 II (F25), BMW X4 I (F26).
