I agree they should have more options for suspension wise, but its all about demand and the main user type of these Theta vehicles are not looking to alter their suspension. I used to own trucks with air ride suspension and lowering components as well as lifted trucks, so i do like that look.
You might want to try to contact company called Eibach, they might be able to make you a set, might be a pretty penny but its really what is worth it to you. A 2-3 drop would look sharpe on a Nox. Just FYI altering your suspension would prob void the warranty, just read the fine print on your bumper bumper or extended. Even ask the dealer or the company what your able to do just to cover yourself.
Only way they would not know if you uninstalled it and put it back to factory every time you took it back to the dealer which would be a pain lol.
Maybe when mine hits 100k I will airbag it and slam to the ground, but the wife prob would not like it lol Id rather just put the money into a old hotrod rebuild.
Good luck!
Yea the springs are not anything electronic. Here is a pic of a 2.4 fwd.
Here is a pic of the 2007-2009 Nox sport version suspension, they look similar to the new ones but not sure if bolts or fitment line up. If so that might work for you because i think they make suspension parts for the 07-09.
