I think you're generalizing a bit too much on low drag coefficent vs down force.
996 Turbo has a Cw of 0.295 and produces a downforce of 6 kg.
996 GT2 has a Cw of 0.32 and a downforce of 8kg.
E46 M3 has a Cw of 0.32 and a NEGATIVE downforce of 18kg
996 C4 has a Cw of 0,30 and a NEGATIVE downforce of 11kg.
Audi RS4 has a Cw of 0,33 and a NEGATIVE downforce of 12kg.
Audi TT has a Cw of 0,34 and a NEGATIVE downforce of 54kg.
Audi S3 has a Cw of 0,335 and a a NEGATIVE downforce of 31kg.
Cheers,

The downforce produced by a vehicle's design is relative to its speed...that's the main reason a car can start to feel unstable above certain speeds, while being perfectly settled at lower speeds.
I believe in Germany it is typical to measure downforce generated at 200 km/h.
