As your NA/NB (1989-2005) Roadster ages, the floor pan of the vehicle can deteriorate from road contact, deformation, and rust. The Shinkai Floor Protection Plates were designed to help alleviate this. The 2mm thick steel plates help increase body rigidity by stiffening the chassis of vehicle. The steel construction of the floor plates adds ample protection against future deformation and acts like a skid plate for the body of the car. The Shinkai Floor Protection Plates are riveted and welded in place to the frame rails of the vehicle and feature an anti-rust black zinc chromate finish. The Shinkai Floor Protection Plates are a great addition to revitalize the feel of the NA/NB Roadster. Learn More
