if you could offset the angle of the hinge slightly so than the door hinges forward-upwards, instead of just upwards you may have an aditional aerodynamic benefit, as the air won't be scooped in the open door when the weels are at a more pronounced angle. does that make sense?

perhaps just a few degrees offset form horizontal in the hinges won't present much additional construction problems (just drill the frontal bolt hole as low as possible in the bracket and the rear one higher) but could yield a slightly better aerodynamic configuration when the doors are opening. in addition the airflow will in part force the doors close at speed

just a thought, it won't make or break the design, but when you go as far as makeing front wheelskirts you light consider these little details as well. respect for attempting front wheel skirts anyway!!!
