wheels, tires, and brakes

I want to know if i change my hubs to a mustangs will i have to use brakes and rotors from the same stang? Also, what's the best size tire to drift with and kind?

The hub swap topic has been discussed many, many times. Search for "hub swap" and you should find the info you need. Also, I doubt you'll find much useful info here on drifting...better you should try a drift specific forum for setup help. Not that I disapprove of drifting or anything, but very few attempt it with a T-Bird. There was one guy on TCCoA who gave it a go a few years back but I'm not sure how that turned out.
