I contacted my Friend John Reed of Reed motorsports. He is a dealer for Menscer and also uses them on his Challenger race car.
He said a good starting point is -
Fronts 6 on compression and 15 on the rebound.
Rears 15 on compression and 6 on the rebound.
All from full tight and back off settings and see what the car does.
They may need to be tightened depending how your car handles that.
