So I've been reading a few different threads where people are saying that springs don't need a settle time, and others saying you do.
On Friday, I put some s tech springs on my car on the front, ( doing the rear Wednesday) and on the driver side it seems to have dropped a good amount, but the passenger side seems to slowly be making its way down.
What do you guys say about spring settle time?

when you notice the ride height hasn't changed?

were they used? or new?

I noticed right away, they've only been on for a few days.

And yes they're brand new
