ok boys.
I go to to describe the work on my car.
First, the car is an Opel tigra, year 1996
It is a little coupè, wit only 1604mm of length.
this is a profile of original car
and this below, it is the final solution (without the wheels), but my girlfriends does not want
My mods include:
1) ugly rear underbody extractor
2) fuel tank area covered with polycarbonate ( the exahust line is not covered)
3) front and rear wheel air deflector: the front deflector, deviate the airflow over the horizontal arm
4) grill block: this use three guideline bearing with manual positioning.
5) I do not know what name to give him, I call it: wheel flow stabilizer (WFS).
I is necessary to study it for a good performance.
A lot problem, it come from the rear suspension axle becouse it is exposed to airflow; I have an idea for problem resolution, but any advice is appreciated
Other problem come from the engine undercover not present.

In red , the final profile
the idea came from looking the underbody airflow of mercedess SLR
Note the air flow in to the rear wheel, wich cause turbolence (in the slr the flow it is used for brake ventilation)
My friend has an engine undercover Audi, but I discovered it
when this cover is applied to the original bumper, the result like below:
