Spring relocation ride height question

I seen somewhere on here that a cuds swar bar would be about the right size..... I remember....





If you move the springs in, your car should sit the same. The springs should have the mounting holes the same height as the stock locations. Now if you do the spring relocating, you will have trouble with a rear sway bar.
Just put a Hotchkis kit with my son on his car. Drop the rear of the car about an inch.
