Toro Rosso add delta wings to STR3

By on

A single event and two weeks after Red Bull introduced their delta wings, Toro Rosso have them too. The design is very much known from BMW Sauber and McLaren although shows most familiarity with the Swiss version.
The wings are built to improve cooling performance and increase downforce, both at the front and rear end of the car.
Also note that the front wing's bridge at Fuji was attached by the older strut, rather than the newer version.
