I wouldn't mess with wheel fairings or fenders - enclose everything instead.
Vehicle's too short to do proper fairings
You'd still have the suspension parts exposed or need large fairings to cover them
You'd get interference drag between the fairings and body
It's a lot of work to fabricate.
Use the width to make a good underbody design that shields the wheels as much as possible,
diffuser on the rear
streamlined fairing aft of the rider's helmet
Why do you use round-section (motorcycle style) tyres instead of flat/squared section tyres (car-like) - to cope with the camber ?
Seems like a lot of negative camber on the wheels - does it understeer with so little weight up front ?
Maybe more contact area on square-section front tires might do the same ?
Or you could further increase the negative camber further and use dual compound motorcycle / scooter tires with better gripping rubber on their sides
Sort of this
