The SPC lower arms have a dropped spring base. Without the use of their shim kit, the lower arm will drop a stock car roughly 1". If you are going to some sort of coil-over where the mount would exist on the flat of the spring base, this would drop the car about 2" as the spiral spring perch is removed completely.
The standard shim kit comes with 2, 1/4" spacers that will adjust ride height up to the factory ride height. You can add additional spacers to the lower or upper pocket if you need, or run a combination to dial in ride height to .5" increments.
This is one area of the SPC arms, that can be a bit challenging. You have a lot of options to dial the ride height, but when dealing with conventional springs, it does add time in labor and guessing to get it right. Especially when taking a car from an antiquated and likely sagging suspension system, to new and modernized.
I don't really like to spend other people's money, but if the budget could handle it, I'd spec a true coil-over from SpeedTech as well, using their Chicane mount.

The Chicane brackets tie directly to the upper control arm mount and adds strength there while providing a double sheer mount for a control arm that is actually stronger than the factory upper spring perch. This is unlike the RideTech and other coilover conversions that use the factory shock mount to hold the weight of the car. That piece is fairly robust on GM cars but it wasn't really designed to hold the weight of the car itself as a stamped steel piece.
