[QUOTE="5.0Black, post: 16534617, member: 172762"] I am assuming this is a 12 GT and not a Boss or something that comes with wider rubber in the rear from the factory. If you are 100% stock outside of the Roush Phase 3 kit contents then adding more power is not the way. Having a high hp/tq engine is cool, but you need a supporting cast of parts to help make use of that power. Your Mustang GT has a 245 or 255 low profile tire on its rear (pending the equipment). 700rwhp, or even the ~575rhwp is not something you want on an at best 255 low profile rear tire. If it was me I would do the below in the order written (or all at once if you can swing it) as opposed to tossing more power at your Mustang. The below will make your Mustang faster, drive better, not sacrifice ride quality and be safer to push to its limits. 1.
