I don't know how Associated would answer that question but I would say it effects everything you listed in someway or another. I believe its mostly a COG thing that effects weight transfer and creates traction or less traction depending on setting. It was an adjustment on the "brand X" FK05 that I used to run for awhile. It is a great adjustment on certain tracks and definately should be tested out. I also remember Gil Losi Jr. once talking about driveshaft angles and how they can create forces on the car.
