I saw this with a 13 year old kid who loved Paul Walker. The final scenes made streams of tears run down his face, and fortunately, I knew what was coming so I had tissues at the ready.
I'd seen the Wiz Khalifa / Charlie Puth video a few times so I knew what was coming: even so, I cried - I cry silently usually - and then I later read a comment on the movie where someone wrote "You guys forgot to mention the significance of Paul's car being white: he was already an angel" and then I lost it.
