Swift Springs Rattle?
 

So I just bought a Z and have some Swift springs installed and noticed some rattling coming from the rear when going over bumps and such. On the highway and stuff don't hear anything but when going over rough areas of the road sounds like marbles sort of in the rear. Is this normal?

Likely not installed properly. Have your installer check it out and make sure it's lined up properly

Check those Bolts for your Sway Bars...

I agree

so the springs aren't supposed to rattle somehwat or make any sounds when going over bumpy roads? Is it supposed to be quiet or how is the drive?

No.

Yes.

If you can have a look and see if all your bolts are tight or take it to whom did the swaybar install to confirm nothings loose.

if not the sway bar bolts anything else you guys suspect? never drove an oem Z so not sure how it drives without the springs but youre saying there should be no rattling or anything from the rear? My GTR rear end rattled slightly but that was a well known factory issue and not a problem so was wondering if this is the same?

Mine never made any noise. My friend installed them and for some reason his made noise...but it went away after a week or so...Not sure what it was

make sure everything was installed correctly and that there isn't something loose inside the car, sometimes a loose clip or something makes it sound like it's coming from the springs

rattling at slow speeds over uneven surfaces (and no noise while driving constant speeds on highways) is usually from endlinks per posts above.

what is an endlink? Does this just require a bolt tightening?

BTW you guys are so helpful!

Did u take the grey peice in the bottom of the stock spring and put it on the new spring?

The bump stops? Yes they were supposed to do that. Can't get under the car to check without a jack/lift.
