Yes very thick plexiglass 3/4 inch I believe. I ordered a front splitter and rear diffuser, he responded right away. Sent me install instructions a video, and a tracking number. They should be arriving Friday I can post some pics when I get them installed.
Package arrived today 1 day late because ups rescheduled it. Was a little banged up bit packaged well enough that everything is fine. Every peice is included, an extra rear fin, hardware, and a torx bit to go with it(making it feel like a genuine vw part). I was able to assemble them tonight but ran out of daylight, hopefully I can finish up tomorrow, wash my car and take some pics. Stay tuned!
Every thing mounted up pretty easily. I ended up taking the front cover off to tighten the bolts. It feels solid and no double sided tape is used, I like that. It certainly gets my approval! I'm messaging the seller now to convince him to start making matching side skirt extensions lol.
