Shuichi Matsumoto

Shuichi Matsumoto (松本 修一 Matsumoto Shūichi) is the personal mechanic for Takumi Fujiwara's AE86 and possibly Chief Mechanic for Project D. He is the driver for Project D's support van #3 during their expeditions. In volume 39 of the manga, Matsumoto was asked by Ryosuke Takahashi to tune his FC for his anticipated encounter with Rin Hojo.

Another thing to note about Matsumoto is his close relationship with Ryosuke, as he is often seen talking to Ryosuke about Project D and Takumi during the latter's races.
