Wheelbase of Vehicle from Percentage Anti Dive
Go Wheelbase of Vehicle = Percentage Anti Dive Front/((Percentage Front Braking)*(Side View Swing Arm Height/Side View Swing Arm Length)/(Height of CG above Road))
Height of Centre of Gravity from Road Surface from Percentage Anti Dive
Go Height of CG above Road = ((Percentage Front Braking)*(Side View Swing Arm Height/Side View Swing Arm Length)*Wheelbase of Vehicle)/Percentage Anti Dive Front
Percentage Front Braking given Percentage Anti Dive
Go Percentage Front Braking = Percentage Anti Dive Front/((Side View Swing Arm Height/Side View Swing Arm Length)/(Height of CG above Road/Wheelbase of Vehicle))
Percentage Anti Dive on Front
Go Percentage Anti Dive Front = (Percentage Front Braking)*(Side View Swing Arm Height/Side View Swing Arm Length)/(Height of CG above Road/Wheelbase of Vehicle)
Wheelbase of Vehicle from Percentage Anti Lift
Go Wheelbase of Vehicle = Percentage Anti Lift/((Percentage Front Braking)*(Side View Swing Arm Height/Side View Swing Arm Length)/(Height of CG above Road))
Percentage Anti Lift
Go Percentage Anti Lift = (Percentage Front Braking)*(Side View Swing Arm Height/Side View Swing Arm Length)/(Height of CG above Road/Wheelbase of Vehicle)
Height of Centre of Gravity from Road Surface from Percentage Anti Lift
Go Height of CG above Road = ((Percentage Rear Braking)*(Side View Swing Arm Height/Side View Swing Arm Length)*Wheelbase of Vehicle)/Percentage Anti Lift
Percentage Rear Braking given Percentage Anti Lift
Go Percentage Rear Braking = Percentage Anti Lift/((Side View Swing Arm Height/Side View Swing Arm Length)/(Height of CG above Road/Wheelbase of Vehicle))
Percent Anti Squat
Go %Anti Squat = (tan(Angle between IC and Ground)/(Height of CG above Road/Wheelbase of Vehicle))*100
Angle between IC and Ground
Go Angle between IC and Ground = atan(Side View Swing Arm Height/Side View Swing Arm Length)
Front View Swing Arm
Go Front View Swing Arm = (Track Width of Vehicle/2)/(1-Roll Camber)
Camber Change Rate
Go Camber Change Rate = atan(1/Front View Swing Arm)
Roll Camber
Go Roll Camber = Camber Angle/Roll Angle

Wheelbase of Vehicle from Percentage Anti Lift Formula

Wheelbase of Vehicle = Percentage Anti Lift/((Percentage Front Braking)*(Side View Swing Arm Height/Side View Swing Arm Length)/(Height of CG above Road))
b = %ALr/((%Bf)*(SVSAh/SVSAl)/(h))

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.
