Designed with specifications that enable drivers to compete in NR-A category races after the addition of special racing kit, Mazda has been selling the base model NR-A Roadster since December 2001. Since then, the NR-A model Roadster has been favorably received by motorsports enthusiasts thanks to its reasonable cost and the added dimension of exhilarating driving possibilities that come with meeting the NR-A race requirements. The new NR-A model Roadster is based on the third generation Roadster that underwent a complete redesign and launched in August 2005. Employing special equipment on the new Roadster NR-A model--height-adjustable Bilstein dampers, a torque-sensing 'Super LSD' (limited-slip differential), and front strut tower bars--makes this exciting new model more suitable for sporty driving.
The manufacturer's suggested retail price for the Roadster MX-5 NR-A model is 2,300,000 yen, including sales tax (16.286,= Euro). It is only available in the Japanese market. The new NR-A model was designed to participate in the "Roadster Party" One Make Races in Japan. These events are sponsored by Mazda and will be held from September 2006.
