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

Height of Centre of Gravity from Road Surface from Percentage Anti Dive Formula

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
h = ((%B_f)*(SVSA_h/SVSA_l)*b)/%AD_f

How is anti dive geometry useful?

When a car is under braking conditions, the braking force acts directly through the centre of gravity and causes the car to rotate. Anti-dive geometry prevents the car from diving on the brakes and stops the front wheels from deflecting vertically or going into bump due to braking conditions. Similarly to anti-squat geometry, the percentage of anti-dive that the car has is based upon side view swing arm length and height, wheelbase and centre of gravity height. If the car has 100% anti-dive then no compression of the front suspension due to braking forces will occur at all. If the percentage is lower than 100% then some compression will occur due to braking forces and will increase as the percentage gets smaller.
