Agreed,ladder bars are not a great idea on the street and they`re especially bad if you want the car to handle. Think of them as a huge hinge,pivoting on the front heims or bushings. The rear axle can ONLY move straight up and down. It can`t twist side to side to follow the road or allow for any body lean so the car ends up skittering through the turns like a big shopping cart. Not fun (unless you`re a kid with an actual shopping cart then it`s BIG FUN! ).
4 link can work very well though. Most factory 4 links use converging arms with much shorter than optimum upper arms and do indeed have some inherent problems. But if you start with a good adj. aftermarket 4 link you can make it work for you. The main thing is to forget about using the diag. track bar or stubby panhard bar they include with most kits and install a nice long panhard bar roughly the same height as the axle tube centerline (for starters) and perfectly level at ride height. Might as well make the mounts adjustable so you can keep it level even if you change the ride height and so you can raise or lower the rear roll center as a tuning aid.
