I have a 2015 C and bought it with 7250 miles on it and driving was like white knuckles, so after some research I added Hellig sway bars, front and rear (got rid of OEM bars) then added Safety Plus steering control, BIG IMPROVEMENT, then added Sumo Springs front and rear, Bilstien shocks and a Supersteer Trac Bar. Yes a few $$$ but seriously no wander, trucks passing and wind barely affects it. It’s a pleasure to drive now. In my opinion the money spent was well worth it but to others some may say overkill.
But I’m very happy with the results. The Trac Bar was the last addition and I am very pleased with that add on.
