Help with antisquat

[shane]

How will I know when to adjust antisquat and what will increasing it do. I mean, what should I notice if that is the only adjustment I make to my car?

anti-squat will help with rear traction on a throttle transition, ie accelerating it will provide more forward bite.

if you find that your car works pretty well all around, but could use a little more grip coming out of the turns and during heavy throttle tire spin, more anti-squat can help.

Thank you jwscab, you are always helpful

I was once told that increasing this by 1 or 2 degrees helps to handle bumpy tracks and jump reception. (Anti-squat is the kick-up on the rear arms , right, not?)

This is going to be long one. Most of these questions are "loaded" questions, because there is really no answer.
Every adjustment on your car works on a "bell curve" of sorts. There is an optimal setting for every adjustment, and how they work with every other setting on your car. You adjust one setting, and it changes the way the other settings work. As with all the settings on your car, the anti-squat setting will will affect your car differently depending on how the rest of your car is setup.
Mechanically, antisquat will allow the rear arms to absorb bumps better off throttle, and it will BIND the suspension under acceleration. How that affects your car, no one can tell you. Sometimes, (usually in high bite situations) you will get more forward bite. But because the rear suspension on the car is binding under acceleration, in low bite situations, you will get LESS weight transfer to the rear wheels, and this will provide LESS rear traction.
No one can tell you what an adjustment IS going to do on your car, only what THEY think it will do. The only way to know is to try it and see. Take notes, and try the same adjustment in varying track conditions to see how your car responds in those situations. I have seen/experienced an increase in antisquat providing my car with more or less rear traction, more or less on power steering, and even (usually) more off power steering, because it aids in forward weight transfer under braking.
One other VERY important thing when making adjustments on a car, is to observe and understand all the other adjustments affected by the change you are about to make. Example, What does moving my rear hubs forward effect? Wheel base, center of gravity, dynamic antisquat (in the form of driveshaft angle), camber (unless re-adjusted), and so on. Point is, that the result you see/feel, may more so be the result of the other unseen changes, rather than the intended adjustment you have made.
I know it may sound like alot, but this is what is involved. -Jeff
