Air-Cooled Endurance: Jeff Zwart’s Safari Rally Challenge

At 70 years old, Jeff Zwart is not a man with many unfinished chapters. Between directing award-winning commercials, redefining hillclimb heroics at Pikes Peak and curating the now-mythical Luftgekühlt gatherings, his life has long existed at the intersection of speed, aesthetics and endurance. When he isn’t flat-out in a Porsche, he’s back home on his Colorado ranch, posting serene images of snow-draped landscapes, air-cooled icons and his beloved Bernese Mountain Dogs.

And yet, even for Zwart, there remained one box unticked.

More than half a century after first reading about it as a teenager, the American Porsche racer has finally conquered what he describes as “probably the hardest event I’ve ever done”: the East African Safari Classic Rally. Not in a modern weapon, but in a competition-prepared classic Porsche 911—exactly the kind of car that helped ignite his passion all those years ago.

For someone with multiple marathon rallies to his name, that statement carries weight. This year’s Safari Classic stretched across nine days and 2,220 competitive kilometres of some of the most punishing terrain imaginable. Heat shimmered relentlessly, dust and mud alternated by the hour, water crossings tested both nerve and machinery, and wildlife ensured concentration never wavered for a second. It is rallying distilled to its rawest form—and that is precisely the appeal.

“I read about this race while I was in high school and I’d always hoped that I’d one day do it,” Zwart explains. “To be able to compete here in a car from the same era as my school days has made the whole experience feel even more special.”

Alongside co-driver Alex Gelsomino, Zwart finished an impressive 17th overall from a starting field of around 60 cars. Remarkably, more than half were classic 911s, underlining just how well Stuttgart’s air-cooled icon continues to thrive under extreme conditions. The overall victory went to British endurance racer Harry Hunt and co-driver Steve McPhee—also in a 911—further cementing the model’s legendary resilience.

The East African Safari Rally traces its origins back to 1953, created to celebrate the coronation of Queen Elizabeth II. Traversing Kenya, Uganda and Tanzania, it quickly earned a reputation as motorsport’s ultimate endurance test. After evolving through multiple formats, the event was reborn in 2003 as the East African Safari Classic Rally, now run biennially for historic machinery. This year’s route carved through Diani, Voi and Amboseli, framed by the dramatic silhouette of Mount Kilimanjaro—beautiful, unforgiving and utterly relentless.

“In the 1970s this was considered the most difficult automotive event in the world, and I don’t think it’s got any easier,” Zwart says, smiling. His early F-series 911 was packed to the roof with spares and tools, a necessity rather than a precaution. “It was super rough and super fast, with lots of wild animals on the course. But the scenery was unparalleled, the people were incredible, and being in a classic 911 just feels like home. Every day the car surprised me with how well it handled things.”

That sense of meaning was amplified by the man in the right-hand seat. Gelsomino was the long-time co-driver of the late Ken Block, who contested the rally in 2022. For Zwart, their partnership carried emotional weight.

“I remember Ken telling me how incredible this rally was. He said, ‘Jeff, you’ve got to do it,’” he recalls. “So to be here with Alex as my co-driver feels like coming full circle. At times it’s been pretty emotional for both of us.”

The rally was far from trouble-free. Suspension damage on day three and a transmission issue late in the event forced the pair to crawl nearly 40 kilometres of a stage in first gear. Yet time loss was minimal, a testament to both mechanical sympathy and the extraordinary durability of the car. Zwart describes the 911 as having taken “an incredible beating” while still running flawlessly as it crossed the final finish line, moments before celebrations on the beach.

Exhausted but elated, Zwart is still processing what he calls “the adventure of a lifetime.”

“It was definitely the toughest event I’ve done,” he says, “but it challenged us in so many ways that I’m incredibly glad we went for it. That said—after all that heat and humidity—I’ll be very happy to be back in the snow.”

Even at 70, Jeff Zwart has proven that some dreams are worth waiting half a century to fulfil—especially when they end, fittingly, behind the wheel of an air-cooled 911.

Porsche 911 GT3 Manthey Kit: Track-Day Royalty Gets Its Crown

In the world of track-day toys, few production cars see as much real circuit mileage as the Porsche 911 GT3. For many owners, it isn’t just a weekend car—it’s a lap-time weapon. But Porsche knows its customers well, and for the most obsessive among them—those chasing tenths, shaving seconds, and living for split times—there’s a new, sharper answer. It’s called the Manthey Kit, and it pushes the already ferocious 992.2 GT3 deep into GT-racer territory.

The upgrade isn’t cosmetic marketing fluff; it’s a ground-up performance overhaul. Porsche and Manthey’s engineers have tackled everything that matters on a racetrack: downforce, suspension, braking, and stability. Consider it the Weissach Package’s overachieving cousin—hungrier, meaner, and laser-focused on lap times.

And those lap times speak clearly. The kit-equipped GT3 circulated the Nürburgring Nordschleife in 6:52.981, slicing 2.8 seconds off the previous Manthey-equipped model despite damp autumn conditions. That’s not evolution—it’s a full send.

Aero: Downforce With a Capital D

The GT3 is already a downforce monster, but the Manthey Kit turns the entire underbody into a single aerodynamic philosophy. Porsche extended the turning vanes under the car by a full meter—to a massive 1.5 meters—creating a broad pressure skirt that sucks the GT3 to the tarmac with ruthless efficiency. Even the luggage compartment floor is now covered to form a completely smooth aero surface.

Up front, a newly extended lip, revised diffuser fins, and side flaps stack on more bite at high speed. Out back, the swan-neck wing grows wider, gains a Gurney flap, and uses enlarged, inward-curved end plates to squeeze optimal airflow. A longer-finned rear diffuser boosts downforce without the usual drag penalty.

Then come the rear carbon aerodiscs, which don’t just look like Le Mans cosplay—they shave drag and complete a fully integrated aero package.

The results are brutal:

  • 355 kg of downforce at 285 km/h in road mode
  • 540 kg in circuit mode (track use only)

That’s race-car territory. No extra drag. Just more grip. Everywhere.

Suspension: Built for Kerbs and Commitment

Track-day driving isn’t just about aero—it’s about how the car reacts when aero isn’t enough. Here, Porsche and Manthey developed a four-way adjustable coilover suspension, designed specifically for circuit punishment. Riders can tune rebound and compression without tools, and the spring rates rise moderately—10 percent at the front—matching the new higher downforce loads.

The payoff? More mechanical grip, better stability through quick direction changes, and real confidence when clattering over kerbs at speed.

Lightweight forged wheels—20-inch front, 21-inch rear—cut unsprung mass by six kilograms and come in three finishes. Braided steel brake lines sharpen pedal feel, and optional PCCB-specific racing pads give serious fade resistance.

This is the GT3 re-engineered for endurance stints, not Sunday drives.

Styling and Extras: Track Toys, Tastefully Done

For owners who want the look to match the lap time, Porsche offers a suite of visual goodies: illuminated carbon sill trims, white Manthey door projectors, colored aero wheel discs, and race-style tow straps (red, black, or yellow). Carbon front air outlets and rear intakes complete the motorsport vibe—though, naturally, some pieces must be removed before heading back onto public roads.

Nordschleife Proven, Notary Certified

Porsche treats the Nürburgring as its proving ground, and the Manthey GT3’s lap time was run by reigning DTM champion Ayhancan Güven—no novice. Even on a partially damp, slippery track, the car delivered a blistering 6:52.981. Both the new and previous Manthey GT3s ran on optional Michelin Pilot Sport Cup 2 R rubber, and the time was officially verified by a notary.

Güven was clear: the new kit transforms the GT3’s cornering capability. “The significantly higher downforce and optimised suspension make the car very easy to control and provide the driver with even more confidence,” he said. Better weather, he noted, could have unlocked an even quicker lap.

Manthey boss Nicolas Raeder echoed him. After a year of wind-tunnel work and thousands of kilometers of European circuit testing, he believes there’s more time on the table—and plans a repeat attempt in better conditions.

Porsche’s 911 GT3 already occupies rare air: one of the few road cars that feels built primarily for racetrack joy. The new Manthey Kit takes that ethos and turns the intensity up several clicks. More downforce, more grip, more stability, and less lap time—it’s the purest expression yet of Porsche’s track-day philosophy.

For the lucky few able to unlock its potential, the GT3 Manthey Kit doesn’t just sharpen the car. It transforms the experience. And at the Nürburgring, the stopwatch is already applauding.

Theon Design 911 Restomod Is a Masterclass in Air-Cooled Perfection

Singer may have lit the fuse on the modern Porsche 911 restomod movement, but the fire has spread far and wide. Across the Atlantic, a handful of British builders have emerged as serious players in this rarefied art form—and Theon Design is leading that charge. Its latest creation, the result of 18 painstaking months of craftsmanship, may just be the Oxfordshire firm’s finest work yet.

At the heart of this Ice Green Metallic masterpiece is a powerplant worthy of a standing ovation. Theon’s engineers have built an air-cooled, 3.8-liter flat-six that breathes through independent throttle bodies and spins out 407 horsepower at a stratospheric 7,600 rpm. Torque peaks at 293 lb-ft (397 Nm), delivered with the kind of immediacy that only individual throttle butterflies can provide.

Those numbers alone might not scare a modern 911 GT3, which enjoys a roughly 100-hp advantage, but the Theon weighs in at a featherweight 1,150 kilograms (2,535 pounds)—a staggering 312 kilos (688 pounds) lighter than the factory GT3. Add in a five-speed manual and rear-wheel drive, and you’ve got an old-school driving experience distilled to its purest form.

And then there’s the noise. Theon’s adjustable exhaust can whisper through the village or wail like a banshee on a Sunday blast, depending on your mood and proximity to the local constabulary. A semi-active TracTive suspension keeps the car composed no matter how pockmarked the road, while a built-in lift kit spares that sculpted nose from steep driveways and unkind speed bumps. Brakes are lifted straight from the 993-generation Carrera RS, and custom 18-inch wheels wrapped in Michelin Pilot Sport rubber keep the classic silhouette planted and poised.

Every Theon begins as a bare-metal 911 shell. The company reworks and strengthens the chassis with fresh seam welding before clothing it in carbon fiber panels that mirror the original’s curves but shed precious weight. The result, finished here in a shimmering Ice Green Metallic with Polished Eclipse Chrome accents, looks as if it just rolled out of Stuttgart in a better alternate universe.

Inside, the craftsmanship borders on obsessive. Recaro CS seats with carbon fiber backs sit amid a sea of gray Alcantara and bespoke leather. The gauges are reimagined yet familiar, while a stealthy Alpine head unit feeds six Focal speakers—modern sound discreetly hidden in a cabin that still feels gloriously analog.

Of course, exclusivity like this doesn’t come cheap. Theon’s commissions start at £420,000 (about $564,000), and that’s before you even source the donor car. But for the lucky few, this is less about cost and more about curation—about owning a machine that captures the soul of the air-cooled 911 and reimagines it for the modern world.

Singer may have started the movement, but Theon Design proves the symphony of the classic 911 is far from over—and in the right hands, it might even sound better than ever.
