Okay...I'll take a different view. It looks like you can move the lower mount outwards instead of moving the upper mounts inwards.
This way you can drive the car as is to see how it does. If you are not happy you only could move the mounts outwards by removing the wheels & coil overs.& welding in new mounts. My guess is that it will be fine as is.

Because the spring/shock is almost straight up you will new less in/lb springs & a roll bar(sway bar).

Let us know how it turns out.
