There is still quite a bit that can be done for the "optional" homologated and non-homologated parts.

Nice summary, two things:
- About the small wings above front wheels. They were probably added because of the extra air coming out of the wheels (due to more open area in front). Thing is the way they are done with the small gap for air from front, the additional air from the wheels increases the speed of the airflow on the underside of the wing (blown wing) which should increase the downforce quite a bit.
- In Sweden it seemed that the ribs in C3 diffuser are now much stiffer since the "flapping" seen during whole 2017 wasn't there so much
Thanks a lot for your great contribution, already incorporated into the post.

Have the rally cars reached the same issue as in F1, where the aerodynamics are getting to advanced, and cornering speed too high?
In F1 it makes overtaking hard, and in rally it moves us towards safety issues for the drivers.
F1 will make changes, will rally?
no.
the end.
