Has anyone had any problems with their rear lowering springs squeaking and creaking at the upper insulator?
That is where the sound seems like it is coming from.
When I take off it rattles a bit like the spring is loose and then it will squeak and creak, when I brake it will rattle.

The car probably has 3,000 miles on the new D-specs and BMR springs and now it is driving me nuts.
Is it possible that the left rear spring has compressed enough to make it to short make good contact?

No. Your shocks will compress fully to let the car sit on the top of the spring. A shock doesn't hold the car up, it simply keeps the bouncing action from happening when you hit bumps. Your springs should not make any noise.

Re-check all the nuts/bolts on the sway bar, pan-hard, shocks and LCA's. Check the wheel lugnuts and brake connections. Then have someone under the vehicle listening and someone over the vehicle pushing down, articulating the suspension, to hear where the noise is coming from. After you think you find it, put your hand on it and you should feel it vibrate. Then do whatever you need to do fix the loose part.

That's how I found my squeak.

I thought it was the poly bushings on my LCAs but I greased them and it was still there.
I then thought it was the left rear shock but it is not that.
I had my brother drive while I had the sits down and my head in the trunk.
You can hear the noise coming from the left rear upper spring insulator, you put your hand on it and you can feel it vibrating.
There is a knocking sound and then what sounds like a metal spring screeching on a rubber part.
I have checked the torque everything and it is all good.

The weird thing is it might go a day or two without making a sound then it will come back and squeak like hell, then it might stop for an hour and then come back for 5 minutes.
There is no rhyme or reason to it and I can’t figure it out.

Oh that is the other weird thing, if the car is on the ground andI articulate the suspension it doesnt make a sound; it only happends when driving, mostly when taking off or braking.
On braking it only makes a rattling sound, on take off or slowing drivingit rattles then sqeaks.
It mostly willonly make a sound blow 30MPH

Does anyone else have any thoughts on this?

Sounds like it could be a sway bar problem, like binding on a bushing.

the squeeking problem is probably caused by your LCAs. By any chance are they Spohn? Because i hace dspecs and pro kit and they were perfectly fine until i installed my Spohn LCAs and now the car creaks when i go over things etc. I greased them plenty yet nothing happens. 100% sure it is the LCAs. hope this helps. Take them off and put stock back on and i assure you yoru problem should go away. I have heard of quite a few people with problems with their spohn lcas.

oh btw mine are adjustable too.

JRT1

Mine are adjustable BMR LCAs.
I had them on with the relocation bracket for probably 750 miles before I got my D-specs installed.
I have probably 3000 miles on them now, what ever it is it is driving me crazy!!!

i get a damn squeak ever since I had my subframe connectors installed. Only happens now and then when I hit bumps on the highway. It sounds horrible. I greased everything with no luck I want to find it very soon though
