Paul Walker -- Fans Rally in Droves ... No Rubber Burned

Paul Walker fans came out by the thousands this weekend for a car rally in his honor ... and to show off their bad ass cars.

The event was held near the site where Paul died ... and the whole thing went off without a hitch.

As we previously reported ... cops were worried the tribute might influence people to drive recklessly -- but instead the fans gathered peacefully, and signed a huge mural for Paul ... and checked out each other's cars.
