98 Chevy Layin out

I am getting the Air Ride Tech, front setup, upper and lower control arms. Will i need drop spindles to allow me to lay out on a stock wheel and will i need them to lay out on 20's? reason being i cant afford rims yet cause im going all out on suspension, so i need to know about the spindles. thanks.

what size tires?

i dont know the size of my tires.. i will have to get back to you on that one because it is at my shop a couple of miles away and it is iced over here..
