Winding out a convertible to 217 mph, we'd imagine, is like flying a Gulfstream V with T-tops. Of course, though the tuning boys at 9ff made such a feat possible, they did it with the top up, mitigating the need for an O2 mask. That means next to a Hemi-powered plain-jane Dodge Charger cop car, the company's all-wheel tuner 911 cabrio is the ultimate sleeper. They make it so by upclocking the factory model to reach 650 hp and boosting the brakes (gee, thanks).
