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 forward traction
- Less “squat” (dropping of the rear end under acceleration)
- Less on-power steering
Less anti-squat (pro-squat is pretty much never used)
- More on-power steering
- More stable in corners
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.
