Driving Characteristics
Compared to the factory AIRMATIC system, the BR Series coilover conversion offers a more direct and predictable driving feel, improved body control, and consistent suspension behaviour under load. The setup is suitable for daily driving while providing a noticeable improvement in handling and stability, especially during spirited road use.
The stiffer rear spring rate helps control vehicle weight and balance on the AWD platform without making the ride overly harsh for street use.

This kit is intended only for vehicles originally equipped with AIRMATIC suspension and is supplied as a conversion solution. It is not suitable for vehicles with factory steel spring suspension.
