The Whiteline W93584 Door Jamb Bushing Kit is designed for 1990–2025 Mazda MX-5 Miata applications, covering the NA, NB, NC, and ND generations. These upgraded synthetic elastomer bushings replace the softer factory rubber door bushings with a firmer design intended to provide a tighter, more solid door fit.
Because the MX-5 is a lightweight two-door convertible, chassis flex can be more noticeable than in a fixed-roof vehicle. Whiteline designed these replacement door bushings to help improve the connection between the doors and chassis, giving the car a more solid feel when the doors are closed.

Whiteline's firmer synthetic elastomer bushings are designed to create a tighter interface when the door is closed, helping the vehicle feel more solid without requiring permanent chassis modification.
