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??
