ok so on any of my other cars I would just buy springs to lower it or coilovers and call it a day. but for this car 03 G35 sedan, people are interchanging 350z stuff and G coupe stuff? Ive read a bit of it but it just makes my brain hurt trying to figure it all out. I just want to lower my car about an inch all around. do I need to replace the struts? are they going to fail soon after I replace the springs?? and some guy said that with some lowering springs the back sags really bad if theres people in the backseat? could somone just simplify this for me?

 

go to the 350z forums and get 350z shocks and springs and it will give u exactly what u are looking for.
