Another question for you guys here, I heard that you can get Nivomat self leveling shocks on the rear as an option with the tow package on a Charger. Is this true? I only ask because that is what I have been told, and it was also said that these cost $350 each. I priced stock rear shocks online and they were either $89 each for with or without touring suspension or $210 each for the performance suspension for the Charger. That does not add up to what I have been told. So are the Nivomats after market then? Can anyone please answer my questions and set me straight on this?
