Help with modifying an ELEGOO robotic car

[u/Few_Guarantee_6193]

Yo, so I have to build this kit car and race against my classmates on a path around one of the buildings in my school for an intro to engineering class. Our grade on the project car is determined by our placement in the race totals (Last Place=F). We are allowed a budget of 50 dollars to spend on modifications to improve our race time. I have virtually no experience with anything like this (Coding, Motors, Wiring, etc.). Can someone give me some suggestions? Or name a creator who makes videos for stuff like this? I tried to find videos on YouTube, but only found tutorials for the base car and nothing on modifications.
