Let me put it this way... if you add canards, the amount of lift your car has is the same, you just added downforce to counteract the lift.
If you add diffusers and underbody plates, you are reducing lift (and drag) by providing a smooth flow of air underneath the car.
A spoiler reduces lift (and drag) by moving air turbulence that accurs in the wake of a vehicle away from the rear of the car.
A wing creates downforce by using drag to push down on the rear of the car.
Two different strategies that work together accomplish the same goal.
