Also, why would a PHR be more advantageous than a Watt's link?

Knowledge is power

Triangulated upper links are a version of the satchell link rear. The angled links should preferably be below the rear for several reasons. One, with the angled links on top, they are usually very short and will bind with very little movement. if they are on bottom they are much longer and less likely to bind. You can cure some of the bind with the use of Jonny Joints. the second reason I have been told is with the angled links on bottom, it lowers roll center height but not sure why. Dennis or Marcus can answer that.

Panhard Bars are better for packaging around exhaust systems. Watt's links are better centering devices for the rear in that they don't allow the rear to move side to side at all. Panhards with enough travel move in a an arc which is side movement. Disadvantage of Watt's is getting the exhaust out the rear effectively. Hope this helps and if I am wrong on anything please correct me. I am a young grass hopper still in training.
