Hello, looks like an old technology has returned but cleverly implemented.
It's listed here:

A big challenge for aero sensitive vehicles is to keep the car level as possible during certain braking situations and rolling situations, this solution does just that, it's an old system that has been bought back in other forms of racing. So sketching it up on a vehicle, there are many ways to do this so this is just an a general sketch:
This could be a highly tunable device depending on how aggressive you want the initial dive to be and how it tapers off after that by varying shapes of the slotted curved plate which was added in this newer iteration. This lets you run less positive castor to reduce tire wear and brake lock up. And to go further, during acceleration, brakes can be applied to resist rear squat and keep the car stable, it's like "blown brakes" or a cheap way to apply wheel load during roll, usually you can't brake into or during turns too much but with this it will apply the load where the driver demands it.
Very interesting. Good on aprillia.
