They'd be within the turbulence of the rear wheels and underbody.
Without attached flow, they cannot provide any pressure recovery, hence, no drag reduction.
That region would be part of a boat-tail integration to the rear fascia.
Clean air would come off the rear skirts and transition onto the gently-tapering sides of the tail, or cavity, providing the flow deceleration that WILL be the pressure recovery.
Until you've belly-panned the rear, and know what you've got to work with on the diffuser design, I'd stay away from any products.
You still have an 'unknown quantity' back there.
