Kazama Auto

Kazama Auto wasn't always the all-round parts producer it is today. Originally only a used car lot Kazama Auto no longer sells only second hand silvias and skylines. Everything from Aero Parts, Turbines, Exhaust Manifolds, Suspension Arms and more are available from this Saitama based car lot. Kazama Auto also participates and sponsers in a number of events held around the Kanto Plan. The most well known of these events would be the D1 Grand Prix, where Kazama Auto competes in the Street Legal series.
If there is anything your car needs, whether its an Aero Kit/Bodykit or some Engine Mounts, Kazama Auto has you covered!
