More than a wheel: a technology platform
The GT TEK is no ordinary wheel. It is a techno-mechanical masterpiece representing 20 years of R&D. BST began in motorsport, but grew into the world's largest manufacturer of carbon wheels. The GT TEK is the result of that evolution: the world's first 100% carbon hollow-spoke automotive wheel. Thanks to advanced materials science, aerodynamics, and manufacturing processes such as those used in Formula 1 and aerospace, BST brings unmatched performance to the road and track.
The GT TEK is designed to optimize the critical properties of a wheel: weight, bending stiffness, rotational mass, and safety. Where conventional alloy wheels often involve a compromise between strength and mass, the GT TEK offers the best of both worlds: up to 60% lighter than standard alloy wheels while being 13 times stronger than aluminum. This combination delivers a directly noticeable advantage in acceleration, braking distance, steering precision, and grip.
The BST GT TEK is not only functional, but has also received award-winning recognition: at the prestigious SEMA Show 2021, this wheel won the award for “Best New Product in the Wheel and Related Products”. This officially placed it in the rare category of ultra-light automotive components – a class containing hardly any other street-legal wheels.
BST uses only high-quality carbon fiber structures sourced from the same supply chains as the aerospace industry. Each GT TEK wheel is manufactured with the utmost precision and individually tested. The production process is fully ISO 9001:2015 certified and audited by TÜV Rheinland. Every wheel has a unique serial number with complete material and production traceability.
This technology is now also used on some of the world's most exclusive supercars, such as the Donkervoort D8 GTO, the Ariel Atom, the VUHL 05, and even the Delage D12 – voted the most beautiful car in the world in 2020. The arrival of the GT TEK in the Porsche 991 GT market means you can now benefit from that same technology – in your own car.
BST is not just a manufacturer. It is a visionary brand that is not satisfied with what already exists. As they say themselves: “We didn’t just break the mould. We shattered it.” The GT TEK wheel is tangible proof of that.
Ultra-light = ultimate performance
The GT TEK wheel set reduces the unsprung weight of your GT3 by approximately 19.4 kg. That means faster acceleration, shorter braking distances, and sharper turn-in – all without compromising strength or safety. The low rotational mass makes your car more agile and responsive than ever, providing an advantage you will feel immediately on the road and track.
BST quality: tested, certified, and trusted
Every GT TEK wheel is produced under ISO 9001:2015 certification and has a unique serial number with complete material traceability. BST subjects its products to extreme testing: from JWL impact tests to track loads with slicks. The wheels comply with DOTE, ETRTO, and TÜV regulations. No compromise, no shortcuts – only complete confidence.
Design with an eye for detail
Technology does not have to be boring – and the GT TEK proves it. The aesthetic is modern, powerful, and unmistakably BST: a subtle mix of aggression and finesse. The visible carbon structure, flowing lines of the hollow spokes, and center-lock wheel nut mounting create a look that matches the exclusivity of your Porsche GT3.
For those who truly make a difference
This set is not for everyone. It is for the purist, the perfectionist, the racer at heart. Someone who sees their GT3 not just as a car, but as an extension of themselves. Someone who understands that true performance lies in the details – and refuses to compromise on them.
Q&A – frequently asked questions
Are these wheels suitable for street use?
Yes, the GT TEK wheels comply with all relevant regulations (DOTE, TÜV, JWL) and are designed for both road and track use.
What is the advantage compared with OEM wheels?
The BST GT TEK wheels are up to 60% lighter, with greater stiffness and improved feedback. This results in improved driving performance and responsiveness.
What about durability?
GT TEK wheels are 13x stronger than aluminum and resistant to impact, fatigue, and thermal stress. They have been extensively tested for long-term use under extreme conditions.
Can I choose from multiple finishes?
Yes, the BST GT TEK wheels can be customized in both finish and color. They are supplied as standard in classic Twill woven carbon, with a transparent coating that beautifully accentuates the depth of the carbon weave. For those looking for something unique, there is also the option of an exclusive Forged Carbon finish – recognizable by its marbled look with more organic lines.
There are three possible surface finishes: high-gloss, matte, or satin (silk gloss / semi-gloss). Each finish highlights the carbon in a different way – from bold and glossy to understated and tactile. The standard color is 'Black', meaning carbon with a transparent clear coat, but for extra character you can choose a tinted coating in Gold, Red, Green, Blue, or even a striking Chameleon finish, in which the carbon changes color depending on the light.
In all cases, an ink coating is used, keeping the structure of the carbon weave clearly visible while adding extra depth and a beautiful color.
Custom colors are also possible, of course. Contact us if your desired color is not listed here; (almost) anything is possible.
Whether you choose timeless elegance or striking exclusivity – your wheels will become a true head-turner that enhances the character of your Porsche GT3.
Are they only for the GT3?
