thinking about purchasing the basis but the modest rear drop is pulling me back

Got a link to this? The only Z's I've worked on were on coilovers. I have no experience modding OEM suspension. I've ridden in and driven Zs on lowering springs, but never installed them on the Z.

EDIT: I found the DIY. That part that is cut is actually completely removed when installing coilovers and replaced by an adjustable metal sleeve. Check the pic below, it's the gold part. You use the green collars and perches on the gold sleeve to adjust ride height.





Some coilovers use a "true coilover" aka "full coilover" in the rear, which completely bypasses the stock mounting of the spring and places the spring right on the damper, like the fronts.
