Model: 1990-97 MX-5 Miata equipped with Tops with Zipper Plastic Windows.

Robbins Part Numbers: 2900,2901 2906,2907 2908,2909

Technical Note:
The plastic window should be unzipped before lowering the Convertible top to avoid creasing or cracking of the plastic window.

Instructions to unzip the plastic window before lowering the convertible top appear in the MX-5 Miata owners manual as can be seen below.

We also strongly recommend that MX-5 Miata owners follow another recommendation listed in the owner’s manual:

"Don’t raise or lower the top when the temperature is below 41ºF (5ºC)."

Lowering or raising the top in cold weather can cause creases to occur in tops and plastic windows, and in plastic windows can easily crack if folded in cold weather.
