Stephani Costanza -- Lapping Up the Sun

EXCLUSIVE

Stephani Costanza is usually speeding around tracks in fast cars -- but lucky for us ... she took her sweet time soaking at the beach. 

We got the former Miss Toyota Grand Prix model out in Venice, where she laid out to sunbathe and eventually got wet in the waves. 

Check out the pics ... Stephani knows how to get the heart racing.
