My son bought a 2016 Nissan Maxima SR from a car lot that already had existing D2 Racing Air bag suspension kit. That kit worked great except for whoever installed them didn’t run the airlines the way I would have as to protect them from damage. So my son kept having air leaking from the lines he need the airbags and I was tire of having to assist him in fixing some else mistake So I wanted to remove the bag for him and go back to stock suspension, however I called Nissan and for me to convert his car back to stock with me doing the work myself would have costed roughly $3k. So in an effort to try and save my son some money. I purchased the D2 racing coil over kit for his Nissan. Installation was pretty self explanatory out with the old and in with the new.
The thing that I would have to liked to see is more detailed instructions as to the ride height adjustment. That section of instructions were different to read and it felt like they would say something on one page and then something different on the next page. So there was a lot of going back and reading over the instructions several times to try and grasp how to correctly adjust the right height.
In all once I took it to my mechanic to have it aligned and have him give it his blessing. The car drives a lot smoother than before. The handling is night and day difference the car is so much more responsive now that it feels like its driving a different car. In all I got what I was looking for by switching from bags to coil overs and for a fraction of what it would have cost me to purchase the stock suspension from Nissan.
Thank you and would recommend these to anyone that asks me.
