I'll bet like it was said before the rear suspension was tightened when it was unloaded.

Any update on this Josh?

Not yet... Took the car back to Nissan and they claim it's not their issue anymore because of the coilovers so I've decided to drive it around for a few weeks to let things settle a bit before taking it in to the tuning shop who does my alignment. Once I bring it in I'm hoping we can loosen the bushings while the car is sitting on the alignment rack and it'll return to its previous ride height. If not I guess well have to do some adjusting to the coilovers. Interesting though that since I got the car back at the raised rear ride height the rear suspension is almost silent where I previously had some knocking before especially at low speeds.

Did they give you a hard time about replacing your subframe? I'm lowered on just h&r springs and they won't replace my subframe
