I just got this email from RD
Dear Danny,
The mold for the E34 front spoiler was broken and beyond repair many years
ago. When we developed a flexible composite about 4-5 years ago we went back
and make new molds for the older low volume parts. We have sold many, many
of these parts over the last 5 years, including parts for E24, E28, and E30
and they have not been considered "cheap fiberglass" because they are not.
If you read the description of this part you will see that we state the part
is composite. We do not think you will be disappointed when the installation
is completed on your BMW.
If I wanted fiberglass parts I would have gone with an ebay bodykit that costs 1/3 of what this bodykit costs.
