The logistics of delivering support for one race car as opposed to three doesn't change too much. There's a certain set of specialty tools and equipment (also staff) that's required to support one car. Supporting two/three doesn't take too much more. For quite a few years, my business provided race support for 8-10 kart racers. Space and logistics for transporting things was probably the biggest concern.
