The one thing about our cars is if you start off on the wrong foot it's a big pain in the butt to go back and start over. If you start modding your Stang without all the information you can find you might go in the wrong direction and decide later you want to use different components. Sub frames are one of those items I would want to make sure I was using the right part for my future game plan. Especially since I plan to do more mods to the suspension. It's best to kind of stay with one company whether it's MM, Griggs, KB, Global West, or whoever. That is the reason for my over informative post. Because I have been researching for the last 3 weeks and am still undecided.
