Racing Service Dino (RSD), our original aerodynamic parts.
Our RSD items modify your Ferrari into a stylish ride in the city while still contributing to driving stability on the racetrack and on the highway. We have developed our own original parts with the idea of maintaining stylish body lines which are associated with speed without losing the high quality of a luxury sports car. Our unique aerodynamic parts respect and even emphasize the original design.

Development of the original RSD parts


`Inspiration from Racing the Ferrari Challenge`

Prior to the creation of our RSD parts, we had participated in the Ferrari Challenge Race in Japan for a total of six years and visited many racetracks in Japan. We were fortunate enough to win the F355 Challenge Series Championship twice and the 360 Challenge Series once.

After the Ferrari Challenge Race, we did not keep the F355 or the F360. However, we were simply unable to forget the magic and the potential of these Ferraris. We always wondered if we had controlled the Ferraris perfectly or not. It stuck in our minds. As a result, we decided to use these racing cars again, for after all, they were the cars we had used to win the Champion Series in the Japanese Ferrari Challenge three times.

Questions continued to haunt us: gIn the approach to that corner, couldnft we change the breaking point at 50 centimeters farther?h, gCouldnft we start accelerating much faster?h We would think, gAt that high-speed corner, professional racing drivers may go through without releasing the accelerator at all.h

We continued to test our modified racing cars on the racetracks and look for the answers. We reached the conclusion that in order to race fast and safely, we needed not only the correct driving technique but also an adequate suspension setup for stable high-speed cruising using increasing air friction.

Some concepts began to emerge. If we gathered all of our technology and know-how gained from our mechanical maintenance and race experience, we could do something to improve the F355 and 360 Modena. We started to test our cars on the Tsukuba Circuit and Twin Ring Motegi racetracks in Japan.

We first developed the aerodynamic parts using downforce to stabilize the vehicle for greater stability at high speeds straight ahead and to calm the driverfs anxiety when going through corners.

At the Twin Ring Motegi racetrack, there is a high-speed left corner turn named 130R right after what we call the First Under Bridge. When we would drive a 360 Challenge on this track with even new Pirelli slick tires, we noticed that we were able to fully accelerate and try 130R on only the first few laps. A few laps later, the Pirelli slick tires started to lose their grip, and we had to adjust the acceleration after checking the tiresf grip condition.

Also, on the Tsukugba Circuit racetrack, we would worry about our rear tiresf condition right after the approach of the final corner. We had not been able to appease this anxiety since we had started attempting the Ferrari Challenge Series in Japan.

However, we installed our newly designed RSD front lip spoiler and rear wing on our cars to improve the downforce. Since then, we have not had to think about what will happen after a few laps. Our RSD front lip spoiler and rear wing effectively improve the downforce so that we do not have to be dependent on the tiresf grip condition all the time.

Since 1998, the regulation of the Ferrari Challenge Race in Japan was changed to allow the use of a rear wing on a vehicle. As a result, racetrack records were improved, and cars showed better performance. However, none of the makers in Japan developed any front aerodynamic parts at that time. Nobody could solve the gunder stealingh problem for the F355 at the mid- and high-speed corners. From these experiences, we developed the front lip spoiler and the rear wing, taking into account the front-rear weight ratio of the machine, which led to a neutral steering response from the machine.
