I will throw in my limited expertise. There is no way, you will get a 99+ GT into low 12's N/A for a couple thousand $$ of bolt ons and suspension work. Since you like to plan everything out, (and I am with you on this, because I do alot of research before I spend the dough), what are your mod plans? Maybe, if you list everything you want to do, the peeps on here can help you out.
