Arizona Z Car Springs on a 78Z

I recently gave myself a set of KYB shocks for Christmas. My 78Z currently has stock springs, but I recently saw a set of used Arizona Z Car springs for sale and was considering installing them along with the KYBs.

So I started searching, but didn't find anything about this combo in an otherwise stock 280. Lots of folks commented about them with regard to the 240s, but not the 280s.

Their website says these springs will lower the 280 1.5 inches.

So my question is will the KYBs work OK with the AZ springs on a 280? My car is a weekend, fair-weather-only driver. Never raced, but wouldn't mind a slightly "sportier" ride over stock. Will also be installing urethane bushings all around at the same time I replace the shocks (and springs, depending on your responses). Thanks in advance.
