does this work for cars with static suspension. (coils)
Yes. Whether eccentric busing (EV Tuning), or longer arms, pretty sure SAS or coil both see benefit.
If you have a coil car, your height is permanently set to about the middle of SAS. Tires may not wear so bad, at -1 degree, uless you're staggering 265's or greater. If you lower with shorter coils, or by "re-ringing" the lower spring perch down ~1", you'll start wearing your insides a lot more quickly (>-2 degrees).
It's early to judge tire wear, but using EV Tuning's bushings in fact did drop my negative camber a full degree. So, "low" setting is like the normal setting, @~1 degree negative. The other thing to bear in mind is, no matter whether you use bushings or arms, you won't drop negative camber much more without running into the limit of rear toe alignment (-that other eccentric will adjust rear toe only so much).
I was going to do a bigger review on these, but my time is being taken up at the intersection of MCUs and avoiding Tesla's updates. I can vouch for EV Tuning's bushings maintaining static camber (digital smart level). Others (earlier in the thread) questioned if the bushing lacked enough torsional play, as they mount to the sub-frame. By virtue of longer (more expensive) arms, retaining the inboard rubber bushing allows closer to the play Tesla allowed. This is a standing concern about using a more firm bushing. What I can say is, I haven't noticed any noises or other problems coming from what remains a rubber on metal interface, back there. Albeit more limited, there is still ~1mm of twist play along the outer diameter of AC Tuning's bushing.
In the end, I gotta say nice job EV Tuning / Electrified Garage!
