Force India took the opportunity at the post Bahrain GP test to assess a few new rear end details that the team then adopted for the Chinese GP.
Either side of the crash structure and within the Y100 limitations the team have been using a winglet to create upwash, at the post Bahrain test and in China this increased to two winglets either side of the crash structure (arrowed).
The team have also made alterations to the Diffuser (circled), with the largest change coming at the outer channels. The outer sections now arc over making the diffuser shorter at its periphery, with the now more complex vertical strakes still outwardly pointed in order to affect the wheels wake outbound of it. The detached Gurney trim also follows the full periphery of the diffuser rather than stopping blunt like the older specification diffuser.
