This has most likely been asked a few times before, but I just want to be completely sure before I go ahead. I have an 04 G35 Coupe, 5at with the sport suspension/package/18" rims. I'm at around 75k and it's starting to feel like an old school caddy. So what I am looking to do is to replace the shocks/struts and springs. I figured that the cost would be low and I can also get a slight drop by going with the oem Z setup. So..my questions are, which Z setup do I need to get? (revised/unrevised, sport/track, which model years..etc)

 

Do NOT buy a unrevised oem Z suspenison and use the shocks that come with it, not under any circumstances. If you going to go that route, make certain that your getting a revised setup that is comming from a 05-07 car.

Not that it's make or break, your 04 doesn't have the sports suspension. Though I understand where the confusion came's from. Infiniti called the regular suspenison "sport tuned". The legit sports suspension didn't come out til 05 and then only on coupes rolling out of the factory on 19" wheels.

Why not just find a used 05+ coupe sport suspenision and install that? You'll get stiffer shocks and stiffer rear springs.
