there isnt enough room under a thirdgen for a bolt in 4 link.
you have to cut out most of the rear floor pan and back half the car

You could do an unequal length, triangulated 4-link system just to be different but it isn't a good performance setup. Some SuperStock cars have an unequal length 4-link because they're not allowed to modify the floor or don't have the room to do it but it's not a triangulated system.

The axle of a third gen sits very high up in the body. There isn't a whole lot of room to do many changes.

You may want to check into a "mini" 4 link. They talk about it on ls1tech. They get hime joints and weld tabs to control arms and axle tubes..connect them and have a lil adjustment. I would just be worried about pinion angle change upon spring compression

thats more like a ladder bar, and very similar to lakewoods traction/lift bar setup. Not the best thing going considering the potential of the torque arm setup
