Racing is the most common theme, of course. It's what the whole Initial D series is about. Another theme is friendship. In fanfiction, we often see the characters' friendships tested and strengthened through their racing experiences.
Initial D is purely fictional. It was created by the author's imagination and doesn't draw from real events or people. The characters and the races are all made up for entertainment.
I recommend "Walking in the Heavens". This book is a novel about the infinite heavens. The protagonist, Xie Yu, enters a strange world with the help of the "gourd imprint" and obtains self-improvement. The first world was Initial D, and later on, it would involve stories from other worlds. If you like this kind of novel, this book will make you addicted.😋I hope you like this fairy's recommendation.

To write a Naruto Initial D fanfiction, start with character development. Consider how the driving skills of Initial D characters would translate to the Naruto universe. For example, Takumi's precision driving could be compared to a ninja's precise jutsu use. Then, plan your story arc. You could have a build - up to a big race event where Naruto teams up with an Initial D character. Add details about the vehicles and how they might be powered in the Naruto world, like using chakra - enhanced engines.
One interesting Naruto Initial D fanfiction could be one where Naruto is a street racer in the Hidden Leaf Village, using his ninja skills to enhance his racing. For example, he might use his shadow clone jutsu to confuse his opponents during a race. Another could be where characters from Initial D end up in the Naruto universe and have to adapt to chakra and ninjutsu.
Racing competitions are a common theme. Whether it's against new opponents from the crossed - over universe or in a combined racing event. For example, if crossed with another racing anime, the characters will often compete to prove who has the best driving skills.
