70 chevelle suspension critique

[bad.samaritan]

I've been slowly ditching my stock suspension for some better pieces and wanted to see what you guys think. Car is a 1970 Chevelle with a BBC. I would like it to mainly handle better on the street, maybe a little auto x time nothing serious.

Rear:
UMI Boxed Lowers
Spohn Adjustable Uppers
Stock sway bar - looking at the hellwig adjustable bar
Stock rear springs.

Front:
Speedtech Uppers/Lowers
Stock height ball joints
Hotchkis sway bar
QA1 Coilovers

Right now the car sits at stock height because I still have 15" Ralley wheels, that would rub if I lowered the ride height. Once I save up for better wheels/ tires I would like to drop the car at least 1-1.5" all the way around.
