I am planning to lower my 85 GT with stock front suspension and a 99 cobra IRS conversion in the rear. I was planning on removing the springs and cutting a coil off of each to lower it. I'm doing this because I'm very short on money and trying to do this on a budget. My question is how far will it lower if I cut one coil off of each spring and if I can even do this with 2 different suspensions. Any help is much appreciated.
