I have a ‘17 MS 100D and swapped over from 19” Slipstreams to 21” Turbines, then added the N2itive lowering link kit and adjustable links. That said, I did not retain the stock toe adjustment.
My experience, you‘ll need both the Camber and Toe arm. There will not be sufficient adjustment in the stock adjusters to compensate; as i presume you are lowering the vehicle as well to correct the Shuddar issue. If you’ve other questions, feel free to ask!!
Oh…and after returning from a 2,800 mile road trip (KSC to Yellowstone) they are worth it. Slightly better efficiency and the 21“s show no abnormal wear. Ride quality isn’t overly affected either. Draw back…they are a PITA to adjust while on the alignment rig.
