F1 teams, and super car manufactures will design flex into some parts for different performance goals. I think the flex on the strut bar is minimal, the carbon fiber hoods and bumpers for the 370z may flex more than the strut bar, but I'm just guessing. Metal inserts can be added for more rigidity. If thats the case, you may as well cover the stock one, or get it powder coated.
