the drivers. I assume this is because there's more weight more often on the drivers side thus the springs/shocks are a bit more relaxed/used so to speak. From the rear, the left(driver) side seemed to be a bit off. Wheel gap in the front was about half a finger MORE on the passenger side. The rear was a full finger. It's never been 100% even for me and several Zs I've seen in person lowered (and some stock) exhibit the same non-perfect wheel gap even on the most level of surfaces. It's lessened somewhat since I had them installed, but it's still not perfect. Give it some time and see what happens.
