Its vinyl mate, although I thought it was pritty good quality lol...
I want the carbon look, but I would really like to keep the genuine Nissan parts. I've seen a few different makes etc of the true carbon ones and some are very poor in quality and fitment. The Nismo ones look the best but they should at nearly £200
I know vinyl isnt the best option and some people would rather have nothing but Ive seen the cheap carbon trim of ebay when people have stuck Nismo stickers on lol..
This is the best stuff I've found without paying mega money. They still fit perfect and all the seal are still on, it has 4 year outdoor warranty and you can wash it with soapy water/ car shampoo with no discolouration.
The vinyl also have a weave feel to it like true un laqured carbon.
My Nismo pillars don't fit as well as my cheapy ebay ones did
