tires/ brakes

Hello guys

I am new to FB and in the process of converting a FC to a FB, so I have a couple of questions

1) I have 6" and 8" wheels, what tires sizes are you using? (Hoosiers)

2) Radial or Bias

3) who's braking systems are you using (4 piston calibers)

4) vented rotor size and where can I buy them.

thanks :(
