In the pantheon of legendary Porsches, the 911 S/T has to hold a pretty vaunted spot. It’s one of the last naturally aspirated P-cars, bundling the GT3 RS’ 4.0-liter flat-six with a back-to-basics six-speed manual transmission and rear-wheel drive. And thanks to a blend of GT3 Touring restraint and GT3 RS carbon fiber, the S/T is the lightest 992-generation P-car, hitting 60 miles per hour in well under 4 seconds. But that doesn’t mean it can’t be improved, which is the angle British tuner JCR is taking.
