J's Racing - Type-S Full Aero Kit - Honda Integra DC5

The conventional aftermarket aero parts are mainly designed for "dress up" purpose and are inadequate as the performance parts for actual road racing or time attack.After its release of S2000 total aero system, J'S Racing spent almost 2 years in research and development for a high performance aero system for Integra DC5.
 
We faithfully followed the traditional J'S method to create the aero system, namely to make the best use of the feedback from the enormous racing experiences. We participated in many races with the DC5 which was equipped with the prototype of the aero system in order to perfect the racing aero system.
 
Not only the Type S aero system possess the essential elements like superior downforce and cooling function, but also it adopts the current trend of utilizing the designs used for the actual race cars.
 
Cooling
It is vital to keep the proper water temperature!
When the water temperature reaches a certain level, the ECU automatically adjusts the program to compensate which causes a significant loss of power.
Due to the narrow inlet of the stock bumper, even a large aftermarket radiator cannot perform its function to the full extent. Consequently, J'S Racing recognized the importance of the bumper inlet design in order to maximize the airflow toward the radiator.

In order to make the full use of the available airflow and to achieve the maximum cooling efficiency, the clearance on the side and lower part are minimized and the shroud is redesigned. As a result, the air speed and volume going through the radiator are drastically improved.

The system reduces the radiator temperature by 8 degree C and successfully prevents the power loss by avoiding the ECU compensation.

* the result was on the test date. It could vary depending on the weather and other factors.
 
Aerodynamics
Best shape for the negative lift
Compared to the rear end with the wing, the front lacks the proper downforce.
Upon that point, J'S Racing drastically improved the front downforce by the following design change.
1) We introduced the front wing style used for the GT race cars in order to increase the downforce from the bumper itself. The bumper is consisted of two separate parts – the upper bumper and the lower front wing.
2) The flat panel design is extended toward the radiator core support The front wing design is more advanced from its of S2000. A diffuser style is used for the DC5 front wing.
 
Furthermore, a carbon front side wing (to be attached to each side of the front wing) is offered as an option.
By keeping the air from escaping to the side, the side wing generates downforce.
When it is used with canard, it increases the air pressure difference between top and bottom side of the canard for more downforce.
The canard is also sold as an option for more downforce.
The canard meets the safety standard with its safer edge style.
It is ideal to set up the side skirt as close to the ground as possible in order to maintain the negative pressure.
However, an extremely close distance from the ground might cause several problems in driving.
Thus, J'S Racing devised a new design to keep the negative pressure without lowering the side skirt too much.
 
First, the side skirt uses the same shape as the front bumper effectively extending the body width. Second, the design minimizes the airflow sucked from the side.
 
The actual body width stays the same.
The jack up point also remains same.
The side skirt consists of two parts.
If the parts should have a contact to the ground and be damaged, you can just replace the lower part. This two parts structure increases the cost performance.
Rear bumper has several ducts (each side of the license plate and each side of the end of bumper) to significantly reduce the parachute effect (a drag caused by the trapped air inside the bumper).
The ducts reduce the drag, which considerably raise the top speed.
The bumper's side fin shape streamlines the airflow on the side and consequently increases the downforce.
 
For a driver who would like a wider front tire, there is an optional dedicated front wide fender available for Type S aero system.
The front wide fender has a duct for streamlining the air, which works for lowering brake temperature and for a higher top speed.
 
Total Aero System
J'S Racing Type-S aero system is an expression of our consistent “Intension”. We strongly recommend a total coordination of all the available Type S parts if the budget permits.
The system will provide an excellent match to Type V or Type S hood and 3D GT Wing*

We wish the customer truly enjoy the excellent performance of our Type S system.
