University of Michigan
One of the things that Michigan does is that they traditionally run pretty much close to stock for everything. This allows them to spend less time trying to debug why things are not working, and quickly swap things out due to having spares. Most of their ability to do well is because of their aero, and the fact that they have an experienced team and run a smooth race.
They also were responsible for inventing the "crush appendage" in 2016 in order to satisfy ASC's crush zone requirements.
