Anti-squat is the angle at which the rear suspension pins are tilted upward at the front when viewed from the side of the car. 0 degree anti-squat indicates the pins are parallel with the chassis. If the front of the pin is angled upward, this is anti-squat, and if it is angled downward, it is called squat or pro-squat.
More anti-squat
- More forward traction
- Less “squat” (dropping of the rear end under acceleration)
- Less on-power steering
Less anti-squat (pro-squat is rarely used)
- Rear of car drops more on acceleration
- Slower weight transfer to the rear on-power
- More on-power steering
- More stable in corners and on bumpy tracks
In the front of the car, the suspension pins can also be angled upwards, in which case it is referred to as kick-up, or in some cases pro-dive.
In some on-road applications, the front of the pins may be angled downward, and this is referred to as anti-dive as it keeps the front end of the car from dropping under deceleration.
