They lower 1", not 0.5"

Another thing to think about is spring rates. The RS*R Superdowns for BRZ lower the car about 1.2" but they are softer than the TRD or RS*R 86 versions in the rear.

RS*R Superdown BRZ
Front 3.16kg/mm
Rear 3.88kg/mm

RS*R Superdown 86
Front: 3.16kg/mm
Rear: 4.49kg/mm

TRD (allegedly Eibach Pro-Kit)
Front: 3.6kg/mm
Rear: 4.9kg/mm
