"Settled" does that mean the car actually drops down a little after the install? If so, how much?
Yeah, pretty much all new springs settle once weighted over a few weeks - manufacturers account for this. The amount depends on the spring and the car. I installed monstrously stiff front coils in my Camaro and they settled very little, other cars I've had it's been about 1/2-1", maybe a bit more.
Good expalanation. I was a bit surprised about this, too, but went into the whole exercise expecting something similar as I had read up on it before my purchase. According to the H&R site, I should expect about a 1.5" drop front and a 1.4 " drop in the rear. That's pretty much where I am. I wanted to maintain a lower CG for track duty (and admittedly looks, too) but I didn't want anything ridiculously low, nor something that would compromise the sweet zone for the Koni Sport adjustable dampers. The Konis literature actually states that they are optimized for a lower-than-stock height and also specifies that this height is in the 1 to 1.75" zone. Just about where thing sit now.
