I used the junkyard front rotors on both my installations, but junk being what it is, I had to buy the rears both times. :biggrin: Yes, buy the brackets, and I think the easiest way to go is to also buy the machined rotors. They come anodised with the extra length 2" studs already installed. The hubs come without new races installed but no bearings, but you can use your existing bearings from your TR rotors unless you must have new. If you can find a 98 thru 02 Camaro in a u-pull-it yard near you, you can get everything you need. That's what I did. Can't say for sure they will work with TTAs, but I think they will. 16" should be enough. And as far as stopping, they are much more substantial than the stock brakes. My pedal on the GN stops with authority pushing down only about an inch. They're awesome. IMO, there really is no comparison to the stockers.
