After installing lower springs, is this normal?
So I installed lowering springs almost a month ago and I'm just wondering a few things. The springs drop the car 1.6" front and 0.8" rear. For some odd reason, the front passenger side is less than a finger gap while the others are 1.5 finger gap. I'm sure the install I did was right though. When driving the car now, every time I hit a pothole or speed bump, there's clunking sounds that I never heard with the factory springs. Does it just need to settle first or what?

On TEIN S-Tech springs the drop should lean towards the drivers side more than the passenger.
It should be a little under a finger gap at the drivers side and about a finger gap on the passenger side. If you don't mind me asking what exact procedure did you use to install your springs?
The only thing I can think of is that the springs aren't seated right in the shock seat, that or the top hats aren't on right. Another big issue is pre-load, if you didn't preload the suspension and reset the bushings before torquing your bolts you make be experiencing a side effect of this.
I can tell you that from the day I installed new shocks and new TEIN springs on my IS, the drop hasn't changed. It is exactly like day one, low and it never needed to settle since I preloaded the suspension using the correct procedure.

The procedure I followed was the instructions on Sewell Parts where they had instructions for installing the F-Sport springs. I can't remember exactly but it was the three bolts on top, loosen the nut, the bolt on the control arm, then the two bolts on the knuckle. Then it the shocks would come out. The springs are seated properly though.
Regarding resetting the bushings, not sure how to do that. I did preload it by jacking up the control arm and torquing the bolts to 80-100? lbs.

Mine aren't the S-Techs. I was about to buy them but then I saw another brand called Hotchkis which makes sway bars for the IS sell their springs for $100 cheaper but with the same exact specs. Same spring rates and drop heights.

It's in the sticky thread at the top of the suspension section:
