And to get that you need some tall brackets. Obviously it also depends on what you can fit under the vehicle.

3 link vs 4 link suspension. Triangulated front 4 link pretty much means your going full hydro. 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. 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. All too often track bars are made out to be an enemy and thats just not the case. Most guys dont need that much adjustability.
A 4 link suspension is geared for adjustability. Either will flex just fine if designed properly. And do some reading about the geometry for them. Still the same old story 3 link if you want to do corners 4 link if you want to point it straight. Theres no better method to setting the roll center height and keeping an axle laterally constrained than a track bar period. 3 link rears are very cool and if executed correctly will perform even better than a triangulated 4 link.
