I think you will spend substantial amount less time messing with a true caltrac setup than messing with a 4 link. Although the 4 link is the ultimate in adjustability, theyre a pain in the *** to get dialed in. And if you put a 4 link in with no anti roll bar, they become much more challenging to handle. Just my opinion and what I have gone through. My car being a very old 4 link car, leaves a lot higher than you would want a 4 link car to leave. But due to my lack of adjustability since the suspension is so old with not many holes for adjustment and big space between the holes, I just found something that I know I can make work and stuck with it.
