Should be between 80-100 from theva. I ve been using it for a year and had remove & assemble back many times to do work on the car. So far no problems, no cracks and material is hard. Surface texture looks like ori and he has stock of that panel. Many people have lost, damage or spoilt the original panel. You might want to put some noise insulation on it to reduce vibration and sound. I also gave theva my old dash board to see if he could custom make a surface layer on the dash board. E30 dashboard is are and if its available then it will cost a BOMB.
Cheers.
