Round tube is stronger just for starters. The RMS unit has a TON of welding in it, and each weld joint puts heat in the material making for an even weaker tube, and then add to that the mounting points of the RMS unit are a square tube cut off, and using the one wall of the tube...A little weird to me. We wont mention the "design" to mount the coilovers.
Again, no disrespect to Bill...I know he sells alot of these.
