And to get that you need some tall brackets. A 4 link suspension is geared for adjustability.

3 link vs 4 link suspension. Triangulated front 4 link pretty much means your going full hydro. Either will flex just fine if designed properly. And do some reading about the geometry for them. Most guys dont need that much adjustability. Obviously it also depends on what you can fit under the vehicle. All too often track bars are made out to be an enemy and thats just not the case.
Still the same old story 3 link if you want to do corners 4 link if you want to point it straight. A 3 link will be fine just gotta make sure its really stout for the upper link and mounts. They are simple to a fault. Theres no better method to setting the roll center height and keeping an axle laterally constrained than a track bar period. A three link could go either way but if you want to keep a steering box you need to go three link with a panhard. 3 link rears are very cool and if executed correctly will perform even better than a triangulated 4 link.
