It's not that easy. If your SUV has huge side mirrors, roof rails/rack, mudflaps, wide tires, etc., then they will spoil the air going along the side/roof, so the Kamm extension will give you less gain. If the sides, roof and belly are smooth, then the same 80% Kamm can be used to its full potential and will give a larger Cd reduction.
