The Porsche 911 S/T has already secured its place in automotive history as evo’s 2024 Car of the Year, but a British performance house believes it’s only just scratching the surface. JCR’s latest creation transforms an already iconic machine into something even more focused, visceral, and desirable—an opportunity not just for purists, but for investors watching the high-end automotive tuning space.
JCR, a UK-based Porsche performance specialist, has taken the revered 911 S/T and created a rarefied version tailored for those who want more—more performance, more aggression, more exclusivity. Though the standard 911 S/T was designed by Porsche’s elite engineering team in Flacht with the road in mind, JCR’s rework pushes the limits of what’s possible without compromising usability. It’s a recalibration of brilliance, precisely honed for those who believe even perfection can be improved upon.
At the heart of the JCR package is a deeper focus on chassis dynamics. Partnering with Cheshire-based Suspension Secrets, JCR has integrated billet front-axle camber blocks that allow for increased negative camber—from -2.5 degrees up to an aggressive -3.8. This seemingly minor adjustment significantly sharpens the car’s cornering behaviour, reducing understeer and tyre degradation while enhancing road and track precision. It’s a setup engineered not just for statistics, but for the sort of nuanced driveability that defines elite performance.
Braking performance is elevated to match. Although Porsche’s standard carbon ceramic system is already world-class, JCR replaces the original components with Pagid RSC1 pads and new carbon ceramic discs from Surface Transforms. Not only do these discs offer improved heat management and braking consistency in both cold and hot conditions, they also reduce unsprung mass—vital for sharper handling. Their layered design also allows resurfacing up to three times, offering extended longevity, a rare feature in high-performance ceramics and a nod to both engineering and economics.
Aerodynamically, the enhancements are as subtle as they are effective. Carbonfibre aero discs on the rear wheels offer both functional gains and visual punch. Meanwhile, the exhaust system has been reimagined entirely. The new unsilenced ‘Race pipe’ with freer-flowing catalytic converters and JCR’s titanium ‘Heritage’ tips doesn’t just make the car sound sharper—it transforms the 911 S/T into a full-blooded road-legal race car. The stock car’s signature howl becomes a fierce RSR-inspired wail, elevating the sensory experience to a new tier.
It’s not just about performance, either. JCR understands the luxury market’s appreciation for detail. New laser-etched satin grey brake calipers and billet nickel-plated mounting bells not only reinforce the motorsport ethos but speak to the craftsmanship expected at this level. Black ‘Heritage’ decals and a billet titanium tow hook lend further bespoke flair. Inside, the seat centres have been reupholstered with JCR’s exclusive Houndstooth fabric, a classic motif that gives the cabin an even more distinctive identity.
With brakes alone topping £15,000, this upgrade package is far from an entry-level offering. But neither is the base car, which commands upwards of £400,000 on the secondary market due to its limited run and instant collectible status. What JCR is offering is a curated performance and visual elevation of an already rare Porsche—perfectly positioned for the well-heeled driver, collector, or investor who understands the compound value of scarcity and engineering excellence.
JCR has carved a niche for itself in the ultra-high-end tuning market by merging British engineering acumen with German automotive artistry. Their Porsche 911 S/T package represents not just a mechanical enhancement, but a considered investment in performance heritage, craftsmanship, and brand equity.
