I'm buying some 350z springs to drop my 2006 6MT coupe 1/2". They are off of an 2005 350z so I believe these are revised springs... When I pick them up is there anyway for me to confirm that they are revised springs?

Thanks!

 

There should be 1 pink dot on the fronts. 1 purple dot and two red for the rear.

 

04.5 up revised rear springs have 2 red dots and one light purple dot. (427lbs in rate)

 

Thanks guys!

The rears the guy brough had a white dot... I looked it up and the white dot looks like it's from unrevised springs... Thanks for saving me from wasting a few dollars!

 

I've got a set of fronts with a pink dot and an orange dot. They were listed as revised as well.

Edit: Also, stock G rears have the same paint markings as revised 350z springs.

 

According to this thread...

Page 10 shows color markings. It seems the fronts were not revised?

Still looking for what white/greens means on Coupes.

Also, I have 2 red/1blue dot springs on the rear now (supposedly revised 2007-2008) but they're softer than stock Coupe, tho they SHOULD be the same. I think they're unrevised due to the ride.

 

In speaking with Leonard at Swift Springs, he too feels that the Z front springs were revised as well, as he recalls they were softer in the earlier models.

He also stated that the 350GT had softer springs than the G Coupe's Sport springs.

Revised sport tuned suspension springs for 05+.

 

Revised? How so?

All data says that Z's and Coupes only had 1 spring. 314 lbs./in. spring rate.

What was revised about it?

Why revise it if nothing changes?
