You can drift with any size wheel and tire just like you can drag race or autocross with any size wheel and tire. The deciding factor is how you want your car to handle and react.
With wheels, the larger you get the heavy they're going to be. Heavier=more mass. The more mass you have to move the more force you need to move it. Acceleration = Force/Mass.
Therefore You can drift with 18"x10" wheels, you'll just need lots of torque to make them spin and lose traction. Thats why D1 cars have so much power, it's not for speed it's to break traction whenever they want.
Tuning a car for drifting, be it engine or suspension is no different than tuning it for anything else. You still have to follow the same guidelines, manipulate the same factors, theres nothing special about it.
If you want to learn to tune a suspension I suggest you pickup a book on the subject.
www.amazon.com carriers a bunch of great ones. I recomend:
"Chassis Engineering" By Herb Adams. It's great for first timers and explains all the basic theory and how most types of suspensions work and how to exploit they're strengths and minimize their weaknesses. And Herb Adams was one of the guys who helped create the Firebird so his credentials are good
"How to Make Your Car Handle" by Fred Puhn. This is one of my favourites. It's more indepth than "Chassis Engineering" with more focus on the practical and real world. How to setup a car for the drag strip, oval, road course or street.
Also, pretty much anything on cars by Carrol Smith is great.
