Never owned a 991 or any Porsche, but have raced Formula Atlantics (240hp, 1000 lbs.). Love my SPF GT40 with 427SR Roush. Think you would find the GT40 somewhere between your 991 and Cobra. Old school suspension, better handling than the Cobra, but not up to your 991. Acceleration equal to your 991, but less braking ability. The SPF GT40 has historical appeal with brutish attitude. If you're thinking of selling both your Cobra and Porsche I'd say go for it.
