Another item you dont want overtighten are lug nuts. I owned a VW Scirocco once upon a time and had new tires put in. The shop that put it on used pnuematic wrench. I sprain my neck and shoulder muscle when I tried to take it off when I had a flat tire in the middle of nowhere. After that incident I've always hand tighten lug nuts and especially oil filters. Especially if you are a DIY kinda guy (person)
