I have been looking out for one of these for some time and the one for sale by a well known parts supplier was in my opinion too expensive so I took a chance and purchased one on ebay from “across the pond.”
I posted a while ago and said I would leave my thoughts on the product.
90-97 Miata R-Package Front Bumper Lip Body Kit Spoiler JDM NA MX5(I assume this is the ebay number - 300736159133)
It appears to be the same material as the original which is described as Polypropylene and comes with all fittings.
It was good enough to fit “as is” though it would be easy enough to remove if I decide to spray it.
The overall cost was around £92 which was £36 for the item, £40 postage & packing and £16 duty I had to pay once it arrived in the UK before they would deliver it.
Make you wonder why a supplier in this country can’t produce them for a similar price?
