QUESTION NEED AWNSER ASAP. (how much to chop off springs for 1/2" drop)

I cut my Macs...1/2 coil was 1/2" drop for the front.....1 full coil was worth 1" in the rear....
Hopefully you got decent struts/shocks as the rides gonna firm up and spanked out S/S are gonna show up with a chittier ride....you 'll notice a dif in the handling to....

Dont forgot to compensate for the rear drop by adjusting the pinion snubber accordingly....otherwise she'll be hitting hard from bottoming out on the snubber...you may need to cut a 1/2" of rubber off to start ??...I would assume you have a shorter snubber from when the Eibach's went in??
 
I would do a half max then try it, then go for more if needed.

Or even get height measurements, cut a 1/4" then reinstall and measure.. Then see where that leaves you and if you want lower.

Remember you can't go back after cutting your springs.
