Rear Diffuster On STR3 and RBR4, Are they The Same???

[ESPImperium]

Im currently looking at the rear diffuser of the Red Bull RBR4 and the Toro Rosso STR3 as the diffrence between both chassis. As i feel that the STR3 is starting to work better compaired to the RBR4.

Im thinking that the diffrence between both cars is so close now, compaired to essencially the same car last year.

Is it the fact the STR3 has had the rear diffuser development that the STR2 didnt get over the RBR3???

I just cannot find a decent picture of the STR3 rear on and i cant find a decent enough picture of the RBR4 for the rear flip-ups as well to compair the cars to each other.

Can anyone help me, or do a pic comparison for both cars.

Thanks.

You are aware that it's the same car but with a Ferrari engine. A ferrari engine that probably works better at some tracks...

Visually they are the same, The RB4 changed earlier this year to a simpler diffuser, without the very tall centre tunnel that split the beam wing. The STR03 was launched in this format and never raced the tall centre tunnel.
