What are the Benefits of Anti Geometry?

Anti-geometries are being used on aero cars. This is because the angle of the underbody was very carefully designed to produce maximum downforce at the set angle. Therefore any changes in the height of the floor pan front to rear would disrupt downforce and therefore massively reduce the grip of the car. With 100% anti-geometry installed it meant that on throttle or brakes the bottom of the car would not pivot and therefore maximum aerodynamic grip was available from the car. Another reason is due to the fact that most race cars have a very low ride height and have an increased chance of bottoming out on circuit. If a car bottoms out on circuit then the suspension suddenly becomes void, the car is slowed down by the increased friction and damage can occur to the underside of the car and any underbody aero. With some anti geometry installed it provides a limiting factor to how much the car can physically dive or squat in accelerating or braking conditions making it very difficult for the car to bottom out.

What are the Negatives of Anti Geometry?

The main drawback to anti-geometry is driver feedback. When a driver applies the brakes in a car they expect the front of the car to dip down. The more severe the dip, the harder they are on the brakes. When they apply the throttle they would also expect the back of the car to sit down slightly. The more the back sits down, the harder they are accelerating. Anti-geometry removes this sensation and provides the driver will very little dynamic feedback under these conditions leaving them feeling only the G forces from their actions. This can be difficult to drive and also difficult to anticipate reaching the limits of grip during braking and acceleration causing an unsettled car. Therefore it is often best to design some squat and some dive back into the suspension system and not run 100% anti-geometry unless the aero dynamics dictate so.
