So I have a set of coupe and a set of Z springs that are mixed up. Can anyone tell me which one is which? Thanks.

 

So I think I've figured it out. In the top pic, the two right with the white dot are the coupe fronts and the two to the left are Z fronts. In the bottom pic, the two right with three red dots are Z rears and the two to the left are coupe rears. Can anyone confirm?

Thanks,

Sy

 

Correct on the top picture, I can tell by the active coil count.

On the bottom pic the 2 red dots and one purple are either revised Z rear springs or oem 2005 coupe sport suspension springs 427lbs in rate. IIRC 3 red dots are a early Z rear spring, then they went to 2 red and one white dots.

 

Yea, the bottom ones are the ones I really need help identifying. I've searched the forums and have come up with conflicting results, but the majority of them I've seen have shown that only the Z springs have three red dots. A few had two reds and one purple. Anyone?

Thanks G! Now I can get started on these!!!

 

As suspension's have changed, so have the color coded dot's.

Any spring with two red and one purple dot is either a revised 350Z rear spring OR a 2005-2007 G35 coupe rear spring from the sport suspension 427lbs in rate.

Perhaps the early 350Z springs I was thinking of have 2 red dots and not 3.

Here's a ad that comfirms 3 red gots are 2003-2007 non sport coupe rear springs

Yea, I'm gonna just say the ones with the three red dots are coupe springs. If they're not then I can always swap them out. The rears seem like a piece of cake anyways.
