JGTC GT500 Underbody Diffusers

The highly competitive racing NSXes in the Japan GT Championship (JGTC) GT500 series partly owe their successful circuit dominance through the underbody diffuser engineering of Dome Co., Ltd. of Japan. Dome has developed these underbody diffusers by studying airflow dynamics of the NSX in wind-tunnel labs. It was determined that the stock NSX has decent underbody airflow management, however, air disruption occurs from open areas under the bonnet, engine, wheel well, and exhaust areas (see diagrams below).

Similar to underbody panels found on road cars such as the Ferrari 360 Modena and F50, the panels placed on the JGTC GT500 series racing NSXes stabilize the airflow under the car, resulting in an aerodynamic surface that works in conjunction with the front canards, spoiler, and various ground effects to achieve optimum down force.

JGTC inspired under body diffusers are available for your street NSX from ScienceofSpeed. Products such as the JGTC Front Underbody Diffuser, JGTC Front Canards, JGTC Front Bumper, JGTC GT500 Style Rear Spoiler, and JGTC Rear Underbody Diffuser are race derived for use on your NSX. Note that aerodynamic modifications to your NSX alters the handling characteristics, especially at high speed. Click here for information on these ScienceofSpeed products.
