The M4 is very long, produces a lot of downforce for fast corners but hates to accelerate from slow speed situations. It also doesn't like to change direction while also slowing down.

Electronics:
TC1 on 4 or 5 for the slow turns, TC8 for everything else.

Adjustments (you dont actually need any imo)

• reduce front bump stop range if braking into corners is an issue, or stiffen front spring.
• move BB forward if too loose into the corners, more front ARB could also help here
• race setup might like a bit of positive toe 

Driving

• Take it easy.
• The car doesnt have to be thrown around. The rear will always have a bit of delay before finding its grip after the front changes direction - wait for that before changing direction again.
• Be gentle in all braking zones that are very late and not very straight. Trailing, trailing and more trailing.
• Keep positioning the car between corners, its crucial.

For races the car becomes more oversteery with fuel, but also more predictable and less nervous. For a full tank lower the rear ride height by up to 3 clicks. 

LFM:
Just reduce fuel load to 45/49L. Balance should become even more neutral. Adjust rear ride height in +-1mm to your liking (higher for oversteer, lower for more neutral behavior).

Hope this helps!
