There are many many more factors than just car and driver, the major factors IMO are
> Power
> The amount of grip you want
> Tyres(width/make etc etc)
> Weight of the car
> Spring rates
> Speed
> The adjustablity of the cars suspension
Althogh the things above are all to do with the car, you could spend days setting up a car, unless the driver can feel and notice the differance whats the point
Il jot down below a range of figers on cars iv set up and delt with and try to explane a bit more. With out giving away too much of course
Front camber range from 3degs to 7.5degs, on any competition car you dont want any less than 3degs camber. 2.5degs for road/drift setup but 3.5degs wont kill any one.
Castor, the more castor you hav ehte faster the steering corrects its self but be carfull, too much castor kills steering lock. Range 6degs to 9degs.
Toe is a bit of a personal oppinion, being RWD 0 is acceptable but for comfort and stability at speed with more than 3degs camber 10-20mins. This all goes out the window as soon as you put any steering lock on so prety pointless on a drift car.
Front camber and castor also have a big impact on how much front end grip/tyre contact you have mid drift.
Rear camber is the biggie yet the range is one of the smallest

+.5degs to -1.5degs. The flatter the tyre tread on the ground the more traction youl have. This is where spring rate also comes into effect, if you have soft springs, when the car squats down under power, the camber will change drematicly. i.e So setting the camber to -.5degs static may become -1.5degs under load.
Toe, the more toe in you have the more traction youl gain, but be carfull, too little or too much can cause the car to handle like a pig. Range 0degs to 2degs IN.
My alignment figgers are top secret
