Some NC1 MX5's may experience a slow retracting seat belt when the belt is unfastened and released.
Dirt or dust can increase the friction between the belt guide in the seat back shoulder area or anchor
area and may cause the seat belt to retract slowly.
The shape of the belt guide has been changed and the friction resistance within the seat belt has been reduced.
We sell this kit as a complete replacement for the guides AND mounting plates for both the left and right side.
*Check second image to see if you need to replace these on your MX5
