So I drive a 2003 350z enthusiast with 160,000 miles and my dad recently bought a 2004 350z touring with 90,000 miles and when you drive them the 04 rides significantly higher... Both are stock ride height with stock suspension. Was the suspension different from 03 to 04? Or is the touring suspension different from enthusiast? His does ride significantly smoother than mine. I was just curious if they had different ride heights from the factory. I couldn't find an answer anywhere.
And here's a pic of the cars sorry it's not too great

 

70k more miles, I would say the shocks and springs aren't holding their own. Probably need replacing soon

 

What he said.
The Enthusiast has 17" wheels versus the 18" wheels on the Touring, not sure if that makes a big difference.

 

I'm pretty sure they're the original shocks... That would explain a lot. But do springs go bad? That's what changes the height...

 

They will sag a bit with age... **** some will even bust in half. Ford tourus and saab springs break all the time.

 

1. The spring age with some sag. not much.
2. Rim size will effect how high it sits.
3. Tire size will effect how high it sits.
4. Someone put lower springs or cut the factory one. Many people that don't want to buy springs will cut them to lower the car. So it will look like factory springs.

 

Which cars got the "revised" springs/shocks? Wasn't it the 2004.5?

 

Correct revised spring rates and bumpstop design in 04.5 but who knows what both those zs have been through.

 

Will driving on worn out springs and shocks make any difference besides bad ride quality and obviously it sits lower too

 

Handling and tire wear are affected.

 

i read a while ago that the 03 sit a little bit lower then the later models
