Should, though I'm not 100% sure about the fronts.

Check the back springs for two red dots and one purple

 

The spring rates are the same, but I believe there's a half inch difference between all 3 models. I think the coupe springs will drop your sedan .5" and the Z springs will drop it 1". I'm pretty sure that's how it goes. Someone back me up here..

 

oh **** you're right, I did read that the Z springs are shorter even though the rates are the same.

Full set of Z revised suspension it is. I'll keep looking.

 

I got a set of coupe sport Springs and a set of revised Z Springs, and the rears were exactly the same length and marks.
The fronts were different marks and lengths though

 

Ah, that could be.

 

Craigslist comes through!

How does this look?

Complete set of 2008 350z springs/shocks with 90k miles.

 

$250 seems a bit steep considering those shocks are next to worthless. 90k miles? They need to be replaced anyhow. I'd see if he'd sell you just the springs for <$150.

 

Noted, thanks.

 

What rims are these?

 

The wheels look like MRR GT1 to me. Hard to tell from the pic on my phone and there are others that are similar.

 

update!

picking up the whole set, springs and struts, for $150

I'll run it the way it is until the shocks truly feel dead.

also found a set of 350z anniversary wheels w/tires cheap.

 

Nice snag, get the wheels too .

 

Has anyone thrown the p0420/p0430 Catalyst Efficiency Below Threshold bank 1/2?

Is there anyway to check whether its a cat that is allowing too much exhaust to pass uncleaned to the secondary o2? or if it is beginning to clog?

On a long highway trip, 100mi or more, the light goes out, and will not return until it is in start stop traffic a while, or shut off and allowed to cool then restarted. I can drive 450 miles through a full tank and it will stay off on a highway drive from OH to NC.

I can hear the exhaust "ticking" as it cools down after shutting it off. Ive driven another G35 at 89,000 miles and didnt hear this. Not sure if its normal or not. Many cars do it, many dont. Not too sure, as i own Hondas, and this is my only G35. My G20t didnt do this.

Car has 212,000 miles, all OEM. Pulls very well, uses less than 1.5qts of 5w30 synthetic oil in 4000miles. Plugs are always very clean, I get around 21-22mpg in the city, and 26-29mpg on the highway.

 

Fukcin A, man. If you got em that cheap just run em. Not bad at all.

It'll actually give you an idea on whether or not you wanna go to Z shocks when they need to be replaced. At the Z height springs you could go with Z or G shocks and kinda mess around with what's best for your comfort.
