Different type of Air suspensions. The AirRunner kit for the G35 is a complete strut replacement, front and rears. Has 4 level adjustment damping settings. Kit is made to fit only the G35 and 350z's. These kit have same structural design as the Lexus and Mercedes Benz air-suspension. Reason why its one of the better air-ride suspensions and why its pretty expensive. These are not for everyone but if you can afford it and want an air-ride kit on your G, I dont recommend going with a cheap set-up.

 

that air runner kit is super nice, i hadnt seen that before. any idea what they go for?

 

Depending on shop, anywhere from $4-$5K. Yeah, its not for everyone. Whats cool is, when parked, I can drop it like a pancake. Can raise and lower it with a wireless remote. Dont have to worry about anyone stealing the car or the rims. When driving, if driving up on steep hill or driveway, just push button to raise front or rear bumpers to protect my bodykit.

 

how is ride quality on freeway or other specific situations? can you three wheel or anything like that?

 

You can set dampers on how you want ride quality. Level 2 rides like stock, I have mine set at level 3, little on stiffer side, I like to feel road more. ......... Roll on 3 wheels? LOL. Doesnt quite work like hydraulics.
