Great post man, nice work. I have a question about a couple things you said. I was under the impression that GT brakes could be swapped to fit on a 2.5i. That the front was a direct bolt on and the rear could be done with slight modification(I believe the parking brake drum and shield)? Is this not correct, as you posted they are completely different platforms?
Also, I don't think the front underbraces from a GT are compatible with our 2.5i for the same reasons that front sway bars aren't compatible.
I am in the process of purchasing a '05 GT brake set-up to put on my '06 2.5i so if anybody knows please share. Also, does anyone know exactly what needs to be done for mods to the rear setup to allow the rear gt brake swap.
