if the ford racing parts are installed from the factory they will be covered under warranty. but i dont think you can get ford racing parts from the factory. there is a whole bunch of threads and posts about warranty issues. if you modify your stang and a after market part , or for that matter a ford racing part installed causes some factory part to fail the warranty will not cover that repair.i just got an 07 gt and you should be fine with what you order lots of power, and might i suggest you order the 3:55 gears . thats what i have in my gt 5 speed and it will move just fine down the road. good luck on your purchase. feel free to message me if you need any more info.
