In the first race, the Supra crashes down after jumping the bridge, and a side shot shows that the Supra's rear wheels have changed from the expensive chrome items to the standard Supra wheels.
There is one error in the Tag Team race: the street is not that long. (I should know, because my dad works on that street.) In the movie, it took a little while to finish getting down that street which was unbelievable, especially at the speed they were going. In reality, if you were to race down that street from where they started (without turning back) it would take you an estimated eight to nine seconds.
