Porsche GT3 & GT4 Roof Box: Introducing the ARKYN GT Mount

The Problem No One Has Solved - Until Now

The Porsche 911 GT3 and 718 GT4 represent the pinnacle of road-going performance engineering. Every line, every component, every millimetre of bodywork exists for a reason. The fixed rear wing that defines their silhouette is not just an aesthetic statement - it is a precision aerodynamic instrument. Which is exactly why fitting a roof box to either car has, until now, been considered an impossibility.

No roof rails. No conventional mounting points. And a rear spoiler that is strictly off-limits by conventional logic.

We did not accept that.

Introducing the ARKYN GT Mount

After months of internal development, we are proud to announce the ARKYN GT Mount - a purpose-engineered mounting system that makes our carbon fibre roof box fully compatible with the Porsche 911 GT3 and 718 GT4.

The GT Mount combines two proven technologies into a single, elegant solution:

• Our battle-tested SeaSucker vacuum system
  The same industrial-grade vacuum cups that have already proven themselves on the Porsche 911, providing a secure, paint-safe attachment to the roof without any drilling, permanent fixtures, or damage to the vehicle.
• A precision-engineered rear crossbar
  A bespoke aluminium strut that interfaces directly with the rear spoiler structure, distributing load evenly and providing the critical second anchor point that makes the system rigid at speed.

The result is a mounting solution that is as uncompromising as the cars it is designed for.

Engineering Meets Reality: Four Days in Croatia

Internal testing only takes you so far. The real measure of any mounting system is not a workshop - it is the open road under real-world conditions, with real variables and no safety net.

So we took the GT Mount to Croatia. Over the course of a four-day sports car rally through some of the country's most demanding roads - long straights, tight mountain passes, and everything in between - our Porsche GT4 wore the full ARKYN setup from start to finish.

The verdict? Exactly what we engineered it to be. Zero movement, zero concerns, zero compromise across all four days.

The Martini GT4: A Fitting Test Platform

There is something fitting about conducting a first field test on a Martini-liveried GT4. The Martini Racing colours have been synonymous with Porsche motorsport since the 1970s - a heritage of performance, precision, and pushing the boundaries of what is considered possible. That is precisely the spirit behind the GT Mount.

Against the iconic blue, red and white stripes of the Martini livery, our carbon fibre box looked exactly as it should: purposeful, clean, and entirely at home.

Why GT3 and GT4 Owners Have Been Waiting for This

GT3 and GT4 owners occupy a unique position in the Porsche world. These are cars bought to be driven - hard, often, and on roads worth driving. A track day weekend, an alpine pass, a multi-day road trip across Europe. These are the journeys these cars were built for.

And yet the moment you need to carry more than fits in the front boot, the options have historically been limited. Compromise on the car you drive, or compromise on the trip. The ARKYN GT Mount removes that choice entirely.

The same carbon fibre box trusted by GT3, Turbo S and RS6 owners - now available for the cars that arguably need it most.

Coming Soon

The ARKYN GT Mount is currently in final pre-production following successful field testing. We will be announcing availability - including fitment details for both the 911 GT3 (992) and 718 GT4 - in the coming weeks.

If you are a GT3 or GT4 owner and want to be first to know when it launches, reach out directly. We would love to hear about the trip you have been planning.
