Built with core race safety equipment including a battery kill switch, fire suppression system, gutted interior, window nets, and multi-point harnesses, the car reflects its dedicated track-use origins. The chassis continues to ride on the Spec Miata Bilstein suspension package, preserving the predictable handling and durability the platform is known for. Power comes from a built cylinder head, managed by a Haltech Elite 1500 ECU, with output measured at 131 wheel horsepower. Aerodynamic and cooling improvements have been carefully developed, featuring a ProCarInnovations rear wing, a custom quick-release front splitter and air dam, and functional brake ducting and radiator ducting designed for sustained on-track performance. To further support cooling efficiency and airflow management, hood ducting has recently been added. Significant mechanical investment has been made and is documented with invoices included in the listing, highlighted by a comprehensive engine rebuild and supporting systems completed by Eccentric Motorsports in August 2025, totaling $10,353 Eccentric Invoice. In addition, the cylinder head build was performed by The Winning Formula Inc., with supporting documentation included. Overall, this Miata represents a well-balanced evolution of a Spec Miata build—retaining its proven suspension and safety foundation while benefiting from documented power, aero, and cooling upgrades.
