I finally got around to installing my S-tune shocks/springs this weekend with the help of a local member. The fronts are sitting evenly and the rear right is also where it should be with those springs but the left rear is approx. 0.4" higher than the right. In other words, it dropped the car half as low in that corner than it should have.

The set up was gently used (1,700 miles) so all 4 sides are fully broken-in and should be at the right height. Stock mounts were reused in all 4 corners. I raised the rear end of the car and visually inspected both sides last night. Left upper mount is exactly where it should be and the spring is seated correctly as well. I am baffled!

Has anyone else exprienced this issue with Nismos? My search turned up a few threads with similar issues but none was about the Nismo set.

Yes my garage is perfectly leveled so it isn't a visual trick I am experiencing. The car is sitting higher in that one spot and barely even looks dropped. I would take pictures but I don't see the point; the issue is exactly as I described.

 

This happened to me when I first installed my Nismo suspension, after a couple of months it all leveled out. Just give it time.

 

Thanks, but in my case there is no question of the springs needing to settle in since they were already fully settled in at the right height on the Nismo show car they were removed from. Evidently, that car sat evenly in all four corners. That's why it doesn't make any sense.

 

How much gas is in it??

 

Should make 0 difference. Think about it. Nismo springs have the resistance of well over 400 lbs/inch. My one spring is half an inch too high, which means gas would have to weigh over 200 lbs and sit right above the left rear wheel well to compress it down far enough.

I know there are dozens of Nismo suspension owners here. How can no one have any input?
