There is the sum up on the design's weight if anybody cares to compared it to the TUV and DOT approved standard for automotive wind deflectors. It is within its DOT regulated 5mm MAX thickness as well. Yes, wind deflectors' sizes & weight are defined by the automotive regulators... if anyone cares to know. There are safety reasons why Porsche and all other auto makers do not use thicker (heavier) materials when engineering their wind deflectors.
I personally think I've done pretty good (+20 s'thing grams, with the adhesive also lollll). The weight of a pack of bubble gum. Anyone care to call the Skybreaker a cheap kit I'll say screw steel
^ There a grab of the complete assembled kit on a scale with a 1g resolution.
^ and there is the weight our original DOT approved PC made glass from Porsche
Enjoy!
