2004 Dakar Rally - Mitsubishi MPR10
2005 Dakar Rally - Mitsubishi MPR11 The MPR11 benefits from improved weight distribution and has a lower center of gravity to improve handling, cornering and road holding.

Citroën Xsara WRC
Kinetic Reverse Function Stabilizer (RFS) The system replaces the dampers of all four wheels with interconnected hydraulic cylinders. The system passively interconnects the front and rear suspension systems in order to optimise suspension performance in both on-road and off-road environments.
Schematics showing how the kinetic developed hydraulically linked passive anti-roll bar system works
The system provides very high roll stiffness while keeping the individual stiffness of each wheel low. Different constructions of the system, passive and active, are available. A design where the front and rear antiroll bars are connected is also available. It got successfully used by Citroën Motorsport in their Xsara WRC rally car. Tenneco – Continuously Controlled Electronic Suspension System (CES) – Better compromise between handling and comfort • Selling price 4-6 times price for standard shock – Combination of Kinetic® and CES – Adds independent corner control, neutral steering behavior to CES technology • In production on the McLaren MP4-12C; in testing with other manufacturers – DRiVTM Digital Valve – Targeting substantial portion of CES benefits for the broader market • Lower total system cost – no dedicated ECU required; improved packaging and reduced power consumption

2002 Cadillac Le Mans Prototype (LMP)
To maximize aerodynamic efficiency at the front of the car; packaging must be very tight. The Cadillac's front suspension consists of the shock, spring, and anti-roll bar attached to the front ofthe tub to stay out of the airflow.
Regressive dampers have high rates of damping at low piston velocities. At a preset threshold velocity — controlled by shim thickness and stack preload — the shim stack "blows down," letting oil pass more freely through relatively large piston orifices. Damping force then "knees over" and remains nearly constant with rising piston velocity.
