hello! i have 2007 v36 G35x sedan, but my rear suspension seems to be the same as Z's.

the problem I have, that I'm gonna change my stock springs to the new ones as my rear sits 1" lower than it should (probably rear springs are too softened now).
I have horrible roads here, so the stock height is what I need!

how do you think, should I change the top conical rubber seats of the rear springs? they are rather expensive (25$ each) and I'm not sure if they can wear at all:


anyway I bought the bottom rubber seats as they are cheap (10$ each).

 

The springs should last the life of the car. Probably the seats or the bushings are worn badly.

 

thanks for fast replying!

when the last time I looked at these rubber seats they seemed to be very strong, as they are armored inside... so, still considering if I should buy the top ones?

 

i dont know if they are causing your heigth issue, but at 25 each, its pretty cheap to add in while you have the shocks off. Cant imagein many people do that more than once in the life of the car.
Be careful as the suspension is NOT the same. The spring rates on the G35 and the 350z are different even though the suspension parts are overall the same.. you want G springs for a G, 350z springs for a 350z.

thanks guys!

of course, I didn't want Z's springs, I will buy the new stock springs to retain the clearance I had

well, I'll think about buying those conical rubber-bastards, though they are avaible in 1 day order and I might look at the old ones to decide...

 

I had 90k on my upper spring mounts and they looked better than the new ones from Nissan that had been on a shelf for 5+years. They are pretty indestructable as I found out trimming them. Plus you can pop them out in about 5 minutes with two 17" wrenches and two jacks.
