I've been away for a while, but I've been getting things together so I can have the stang ready for the summer. I'm getting lowering springs, shocks and struts probably in the next 2 weeks. Next the wheels and another radio. While getting this done, I am considering getting a pulley to get a little more out of the car. Since I'm no genius or even consider myself to be a whiz in this area, I'm coming to the pros to kind out what is a safe and recommended psi that I should try to achieve and how?
