TECHART GTStreet R Flyweight: The Upgraded 992 Turbo S To End All Non-Hybrid 911 Turbos

Making the quickest 992 even quicker

When talking about any TECHART package, we have to start with the performance gains. The GT Street R Flyweight is essentially a fine-tuned variant of the regular GT Street R, that we got back in 2021. It is worth noting that this is not the only treatment for the 992 that TECHART offers. There is also a convertible variant of the GT Street R and more recently, the German tuner introduced the GT Street R Touring, which features slightly more restrained performance enhancements and a more classically-correct body kit, featuring a ducktail rear spoiler.

The Porsche 992 Turbo S is already an insanely capable platform, able to reach 60 mph in as little as 2.5 seconds or 2.2 seconds if you have Porsche’s optional Lightweight package. That said, the GT Street R benefits from upgraded turbochargers, new active sports exhaust, sports air intake, reinforced overrun air valves, and bespoke software to make it all come together properly. Given the capabilities of Porsche’s T-Hybrid powertrain, we know the upcoming 992.2 Turbo and Turbo S will also be hybrid, but TECHART may have a better solution for those who aren’t as enthusiastic about the electrification of the 911. The new numbers dwarf even the already-capable 992 Turbo S, as seen by the side-by-side comparison, below.

The performance enhancements are not limited to the engine bay. They also include weight reduction, aerodynamically-optimized body, and revised chassis – more on those in a bit. The GT Street R Flyweight is roughly 132 pounds lighter than a similarly-equipped Porsche 992.1 Turbo S. While the 0 to 60 mph time really cannot be improved by a lot. But it is the 0 to 124 mph (200 km/h) time that’s truly impressive – 7.5 seconds, which is a full second quicker than the stock Porsche 992.1 Turbo S.

The Flyweight enhancements

In order to explain TECHART’s Flyweight treatment, we first have to start with what makes the regular GT Street R. We aren’t just talking about the aforementioned performance modifications. To match the new engine output, the chassis and aerodynamics have been extensively revised. TECHART GT Street R features new coil-over suspension, co-developed with known performance suspension manufacturer, Öhlins. The setup is highly adjustable, allowing for changes in ride height, rebound, and compression damping, making the car just as suitable for the race track as it is for the road. One of the more controversial engineering decisions in the 911 is the choice of McPherson-type front suspension. TECHART has replaced it with an optimized, wishbone setup for better control and improved response.

Like the regular GT Street R, the Flyweight still retains the Turbo S’ all-wheel-drive capabilities. However, thanks to the new calibration, power delivery is now more responsive. The handling upgrades are rounded off by grippy, Michelin Pilot Sport Cup 2 R tires. The way TECHART went about fine-tuning its 911 Turbo S-based model is similar to Nardone’s pedantic approach to reimagining the Porsche 928.

The GT Street R Flyweight squeezes the maximum out of every component. As the name suggests, the treatment is all about shedding weight from whenever possible, without sacrificing the refinement. TECHART mentions a weight reduction of about 60 kg (132 pounds) and some of it comes from the new, Formula VI Race Flyweight forged wheels, which feature a thinner spoke design compared to what you would find on the early GT Street R variants. The wheels measure 9.5 x 20 inches front and 12 x 21 inches rear.

The weight per wheel is 21.6 pounds (9.8 kg) for the front ones and 24.7 pounds (11.2 kg) for the rear ones, which is a weight reduction of over 5.7 pounds (2.6 kg) on the front axle and 4.85 pounds (2.2 kg) on the rear axle thus greatly reducing unsprung weight. The valved sport exhaust of the GT Street R Flyweight has been further revised. In addition to producing orgasmic notes, the system is now nearly 6.2 pounds (2.8 kg) lighter than on the base GT Street R.

Clubsport interior with extra emphasis on motorsports

No doubt, the few lucky owners of the GT Street R Flyweight will be spending a lot of time in the cockpit. TECHART has ensured that sitting behind the wheel is a special occasion. “Luxurious and Puristic” is how the company describes the Clubsport interior of its most radical, 911 Turbo S-based model. The interior plays to the Porsche 911’s motorsport and luxury roots, combining high-quality materials like Alcantara and carbon fiber in a way that’s both purposeful and luxurious.

TECHART worked closely with Recaro, which recently filed for bankruptcy. They developed the RECARO Podium CF performance seats, featured in every GT Street R Flyweight. The carbon-fiber seat shells weigh just 10.8 pounds (4.9 kg) each. Another neat feature is the 3D-printed seat paddings, co-developed with OECHSLER. Unlike the base GT Street R, the Flyweight comes with FIA homologation, six-point racing harnesses, rear-seat delete with carbon-fiber shelf, lightweight carpeting, and a custom steering wheel. TECHART offers an extensive array of customization options, ensuring none of the 19 examples are truly identical.

The aggressive body kit isn’t just for show

The TECHART GT Street R Flyweight carries over the standard GT Street R’s aggressive body kit, featuring vast amounts of exposed carbon fiber. A pronounced front splitter rounds off the new front apron, featuring larger air intakes and extra fins to direct air alongside the body. The new front end works with the new, carbon-fiber hood, which features additional air extractors. The front fenders now have air extractors, akin to what you normally get on the track-focused Porsche 911 GT3 RS.

New side skirts nicely transition to the rear bumper, which now features a large diffuser, with twin exhaust tips, positioned closer to the middle. By far the most obvious addition is the twin-stack, active rear spoiler, which makes the modified 911 Turbo S look like a star fighter from a Sci-Fi movie. TECHART did extensive wind tunnel testing to optimize airflow. This resulted in the GT Street R Flyweight’s body producing four times more downforce on the rear axle while reducing front-axle lift by 45 percent, at 87 mph (140 km/h).

The price of exclusivity

The original GT Street R treatment from TECHART costs $85,000 on top of the donor 911 Turbo S. The Flyweight refinements are likely in the neighborhood of $100,000, turning the 992 Turbo S into a potentially, $300,000-plus sports car- great bang for the buck considering something like the ever-elusive Porsche 993 Speedster can cost as much as $850,000 if you get Gunterwerks to reimagine the iconic open-top Porsche. Considering the performance advantages and exclusivity, I think TECHART’s GT Street R Flyweight is money well-spent. Whenever any of the 19 examples pop up for sale, I imagine it would command a hefty price tag.
