Tein Street Basis Problem... No clue what it is...
 

I've had my new coils on the car for about three months now and they have been great... Except this morning I noticed that the rear driver side dropped between a 1/2 inch to an inch... Both rear coils have 6 threads left... I took a look at it and the coilover is intact.... no issues that I can see.


Does anyone know how the coils are set at the same positions, but one side is this much lower than the other... Pleas help...

Go back and retorque everything. It's not uncommon for this to happen, and retorquing would be a good place to start. Another tip is to mark the adjusters to see where things are coming loose/undone.

How are you measuring your threads? It could be that the preload is different between left and right. Maybe the preload on one of your coils slipped and so there is more droop

Okay
I'm
So
Surprised some **** head hasn't posted a stupid comment " that's what u get for 650$"

Well now that you mention it...
