Odd brake conversion question

[The Stickman]

Ok I have a chance to get a set of Ex-NASCAR Cup brakes in trade for something I am trying to sell. They are complete hub, rotor and caliper assemblies. From what I know at this point they are 12 inch diameter rotors that are the thick short track spec pieces. They are 4 pot calipers. I would be getting 2 complete sets. They are on complet hub assemblies which I will address in a suspension thread. Now the rotors are 5X5 bolt pattern which is what I have so that makes them more appealing. I would like a bigger diameter rotor but the mass of these will help probably more tan a larger rotor would so brake cooling should be excellent with these. Bascially I am wondering pros and cons of this potential set up. I might not be able to get the cash for what I want to afford the brake package I want so a trade for true race parts would be a god deal to me. I am open to opinions as to wether this will work or not.
