Pushing the envelope

Few cars in recent memory have captured the attention of driving enthusiasts like the Porsche 718 Cayman GT4 RS. It’s Porsche’s ultimate expression of what a mid-engined Cayman can be – razor sharp, wildly engaging, and deeply engineered for track precision – and crucially only a hair’s breadth away from the legendary GT3 in terms of outright ability.

Powered by a high-revving 4.0-litre naturally-aspirated flat-six engine producing 500PS and 450NM of torque, the GT4 RS can complete the 0-62mph sprint in just 3.4 seconds and keep pushing on to a 196mph top speed. A slick-shifting seven-speed PDK dual clutch transmission with torque vectoring and a mechanically-locking rear differential ensure optimum drive whether on the road or track.

Of course, the very nature of any machine wearing the hallowed RS badge is that it comes loaded to the gills with Porsche’s top performance enhancing equipment straight from the factory. But, for those in the know, there’s one spec that pushes the envelope even further: the Weissach Pack.

What is the Weissach Pack?

The Weissach Pack takes the Porsche GT4 RS to another level of exclusivity and track-focused detail. Named after Porsche’s motorsport R&D facility in Germany, it adds a collection of lightweight and motorsport-derived components that enhance both performance and presence.

As a £12,305 upgrade, the Weissach Pack swaps the standard RS front lid, air intakes and rear wing for items made from lightweight carbon-fibre. The exposed weave gives it a hardcore motorsport look, while the weight reduction further adds to the car’s already impressive performance stats. The exotic composite is also utilised on the fixed bucket seats, which are trimmed in black leather and Race-Tec with Weissach embroidery, electronic height adjustment and are complemented with a set of racing harnesses.

These track-inspired seats are cocooned inside an interior protected by a titanium rollcage, while the lightweight alloy also features on the exhaust tailpipes.

Lightweight forged magnesium wheels are available as an £11,573 option and not only look spectacular, but help reduce unsprung mass, further enhancing the car’s dynamic ability.

The visual impact of the carbon elements and Weissach-specific details make the car feel even more special and motorsport-inspired than a base RS, but there is a small question that arises…

Is the Weissach Pack Worth It?

While the base GT4 RS is already a sensational machine, the Weissach Pack elevates it to a true GT icon. It doesn’t change the core drivetrain, but it enhances the car’s aerodynamic performance, reduces weight, and adds a layer of visual aggression that brings it closer to Porsche’s GT2 RS and GT3 RS heritage.

From a resale perspective, the Weissach Pack is already proving its worth. It’s not just a styling upgrade – it’s a future-proofing investment, where cars equipped with this exclusive add-on are consistently outperforming non-Weissach examples when it comes desirability and therefore resale values.

Own a Weissach wonder

As passionate automotive enthusiasts ourselves, we know the desire to own a unique and exclusively specified machine is of extreme importance to both car collectors and petrolheads alike, which is why we’re delighted to offer one of the finest examples available today – a low-mileage, one owner, Porsche Cayman GT4 RS finished in a stunning colour combination, fully equipped with the highly sought-after Weissach Pack. This is a rare opportunity to own what is widely considered the most desirable version of an already iconic car.

Why This GT4 RS Is the One to Have

The car we have in stock isn’t just a GT4 RS – it’s the GT4 RS you want to own. Carefully specced with the Weissach Pack, it stands out not only for its performance and presence, but also for its investment potential. As more GT4 RSs hit the used market, Weissach-equipped cars are commanding a significant premium – and for good reason. They’re rarer, more distinctive, and provide the ultimate from the factory level of performance.

Boasting just 1,156 miles from new and coming with full Porsche main dealer service history, this extraordinary 2023 Porsche 718 Cayman GT4 RS is presented in the striking Arctic Grey and is equipped with over £35,000 of factory options, including not only the Weissach Pack, but also the optional forged magnesium wheels in Satin Indigo Blue, front axle lift, BOSE surround sound system and PDLS lighting system.

On top of this stellar factory spec is a host of aftermarket upgrades that further mark out this example as standing head and shoulders above the rest. These include a host of carbon-fibre parts from Automotive Passion such as the rear wing endplates, the oil and water cover, the seat bolster protectors and the seat recliner brackets.

Keeping this glorious machine looking its best is a full car covering of self-healing XPEL paint protection film. This durable transparent polyurethane film was fitted from new and covers every single body panel, resulting in the car’s flawless finish remaining intact with no stonechips or scratches – even select interior parts have been similarly protected too!

These highly desirable upgrades, combined with the factory options and Weissach pack, means this example represents the ultimate version of an already world-class machine. Whether you’re buying to drive or to collect, this is the spec that future buyers will be chasing.
