What is the max stock spring lift
Hi Greek Guy! Take a ride down to your local library where I'll bet you'll find the Chilton's manual for your 1991 Mustang. That will give you the values you need. If that's not an option for you and you don't want to ask your local Ford Service Manager you can give what will be a very enjoyable call to Pat at Mid-Country Mustang in PA at 1-800-358-8081. These guys are the Mustang gurus. Good luck!
