suspension term definitions anti's actions

Ackerman\

 Steering kinematic characteristic where inside front wheel turns more than outside 

front wheel. 0% Ackerman is parallel steering; 100% Ackerman defines all 

four wheels pointing at a common center; Anti-Ackerman has o/s front 

wheel turn more than i/s front wheel. Street cars have 40-80% Ackerman; 

race cars have up to 20%, sometimes anti-Ackerman. [Front steer, rear steer, 

tie rod, upright]. 

 

Anti-Roll Bar

Suspension device, usually a round bar with lever arms at ends, which acts to 

reduce the roll angle of the vehicle under cornering loads. Also important for 

adjusting the balance of the car. Aka: stabilizer bar, stabar, sway bar. 

[Balance, oversteer, understeer, neutral, roll stiffness]

Anti-Dive:

 Front suspension kinematic characteristic which reduces the amount of pitch under 

braking forces. 100% antidive refers to no change in front suspension height 

under braking.  Achieved kinematic ally by processing the wheel in bump.  

If  excessive, will tend to bind up suspension under bumps. Street cars have 

20-40% antidive, race cars 0-30%.  [Precession, recession, pitch]

Anti-Lift

Rear suspension kinematic characteristic which reduces the amount of pitch under 

braking forces.  Street cars may have up to 150% ant lift for driver comfort. 

[anti-dive, pitch]

Anti-Squat:

 Rear suspension (on RWD vehicles) kinematic characteristic which reduces the 

amount of pitch under acceleration. Achieved with recession.  Street cars 

have up to 50% antisquat, race cars up to 30%. [anti-dive]
