If you are starting from scratch then rear disc might be a better deal but you need to be careful what you buy. I wouldn't recommend Wilwood for the rear unless it is a drag only car.
Check with DoctorDiff. I think he has everything you need and if you buy from him it will actually work.
Are you going to have an emergency brake? If so, that will force you to make some choices. Drum brakes come with the emergency brake but disc brakes usually don't.
I want an emergency brake for the car. Are you saying you wouldn't use the wilwood dynalite kit or you wouldnt use the wilwoods at all? They do make a street kit that comes with a parking brake too.
