You can get some of the squat out by playing with bar lengths and pinion angle, and a bit more with springs and shock valving.... Squat is not the ultimate way too hook a car up, but lots of time with a parallel 4 bar it works the best.... With the bars being equal length and parallel, sometimes it's just something you have to live with... On a drag car, with an unequal length non-parallel 4 bar you can make it do anything you want....but with all their adjustability it's almost too much hassle on the street.... Just another of those compromise things we have to live with on the street.....
