Anti-Squat

What is Anti-Squat?

Anti-Squat is basically caster for the rear wheels. It is measured from horizontal when looked at from the side of the car. 0deg of Anti-Squat means that the rear arms are level with the chassis, while 2deg of Anti-Squat means that the front of the rear arms are angled up higher than the chassis. Adding Anti-Squat lets the car 'Squat' under acceleration, providing more traction in a forward motion, or on power, but will reduce traction off power, or into turns. The more Squat, the more forward traction. Removing Anti-Squat will give you more on-power steering, but will make you car push a little more going into a turn. Less Anti-Squat will also improve acceleration under bumpy conditions.

How do I change Anti-Squat?

Anti-Squat is easily changed on most vehicles. On the TC3, it requires simply removing the rear arm mount (R+3+2) and changing it to the optional R+3+0. On other vehicles, you might have to remove the rear hinge pin and re-position the rear arm mount to another set of holes. In off-road, sliding small washers under the front of the rear arm mounts will add Anti-Squat. Typically, 2deg of Anti-Squat is the norm.

For faster rear arm mount changes, try this tip. Remove the REAR bumper from the car. On it, you will see 4 holes. With a sharp pair of sidecutters, nip the plastic so the 2 outermost holes will be removed. Re-install the bumper. The next time you need to change the rear arm mount, all you need to do is remove the REAR ARM MOUNT SCREWS, and the rear arm mount and bumper will slide right out.
