Firstly i know fender skirts will decrease cd (drag coefficient) but i am questioning if they can have affect on cl (lift) do they decrease lift and create downforce or they dont have a impact in other forces. i want to run this in cfd simulation but i cant have some issues.
what do you think ?

I was without transportation for 11-days, and had time to dig around in my archive.
I could find zero references which attributed wheel skirts to 'lift' of any kind.

Directional stability 'WAS' mentioned, as with the fully-skirted 1985 Ford Probe-V concept, in which the lead aerodynamicist reported that the car exhibited no handling issues at high speed, crosswinds or not.

If your CFD software is capable of registering drag, lift / downforce, pitch, roll, or yaw moments, they'll show up, or not, depending on the body architecture.
If the original OEM data cloud is modified to include skirts, then, if any of these forces are altered by the presence of the skirts, they'll just be represented as new information after the post-processing data reduction. I don't see how it can be an 'issue'
