It's across world trade center & kart trax in roxas blvd.
There's another event scheduled to happen this July 20.
Admission is free, it's from 830am-whatever time it takes for the last car to run.
The best time to go there to watch is around 1030am.
Just look for the dust being thrown up by the cars.
Ungas,
