Hermie, I'm not sure why you have such a fear of front end lift on your car.
Have you been involved in an accident in which the car became airborne ?
( I have - I hit a culvert going too fast, and did a 'Dukes of Hazzard' .)
If you want to design your car to have a well balanced Cl, as well as Cd, look to cars such as the McLaren and Ferrari.
Note the absence of wings on two of the cars in the image.
