For this one, the idea was simple: I just wanted to throw on
every upgrade I could onto this thing, even the hidden parts, and ultimately maximize its performance. While the Red Bull X2010 doesn't have many parts you can buy for it at all, I've known for many years that switching the body of a car to one that does allow said upgrades would allow me to buy them for this car, despite it not originally supporting them. So I did that and went through several bodies to achieve this until I had everything I could get my hands on. Something interesting I noticed while using a different body is that by uninstalling the racing exhaust it has preinstalled and then reinstalling it, it gave me a boost in HP! I'll admit, I don't have the hidden brakes installed because I don't know any cars that allow them, and it's possible there may be more hidden parts I could add that will work, but for now, I am calling it finished.
So the car basically has every upgrade installed I could get my hands on, including hidden parts, a tweak to the transmission to achieve the highest top speeds, and I changed the steer limit to FF so it wouldn't understeer as much from the high speeds. It even has both a turbo and a supercharger installed.

Once all that was done, I took it on an endurance race to break it in. And here's all of my in-game settings:
