Blu could speak to this better than I can, but pretty sure the rotors Dr. Diff uses in this kit are really pretty deep. It's not the shallow Mustang rotors. I don't remember the difference in offset, but I should have it somewhere. Either way, I doubt you would have an issue.
You can kind of see the difference in this picture Blu posted.
BTW, your car is another that I use as an inspiration. Just an all around great build.
