AS demo cars are developed in order to grasp the advantages and disadvantages of modified cars with high performance parts, and the collection of data based on the performance limits and safety margin. This data collection is conducted by the head of AS and its chief tuner. We have been conducting testing for many years now and pride outselves in having participated in a large number of races personally without the need to hire a pro race driver and thus gained experience. Our recommendations are based on the user's standpoint. In terms of street-race car tuning, we provide our customers with reliable support, practical techniques on the high-speed driving, and risk avoidance based on our long experience.

The "Yellow Silvia" was developed for the purpose of setting records in the 2000cc rear wheel drive field. This particular engine emphasis is on maximizing the torque characteristic. The engine's power is kept within the limit of the normal drive train. We have made efforts to lighten the car, reduced the front weight so as to make the rear and front weight equal. We achieved 10.761sec at the Central circuit 0-400m race in 1998 June

The RX7 is well-know for its cornering abilities, and is always among the best in lap time ranking. We tuned this car called "Black Eagle" in accordance with the uniqueness of AS styling without making sacrifices in equipment like air-conditioner and audio etc so that it is both enjoyable as a street driven car as well as a circuit racer.
