Made for your Jeep
These wheels were specifically designed for the Wrangler JK and take the unique track width, geometry and driving characteristics of this model into account. Thanks to the ET value of -8.8, they fill the wheel arches beautifully and give your Jeep that iconic wide stance. The adapter set ensures that the 6 x 135 mm wheels fit perfectly on the original 5 x 127 mm hub, without compromising safety or functionality.
Performance gains you can feel
Thanks to the low unsprung weight, you will immediately notice a difference in acceleration, braking distance and steering response. Off-road, you benefit from the additional suspension comfort and vibration damping that carbon naturally provides. On asphalt, you experience a quieter and smoother ride, with less fatigue during longer journeys.
More than a wheel: a technology platform
The GT TEK is not an 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 unparalleled performance to the road and track.
The GT TEK was designed to optimize the critical properties of a wheel: weight, bending stiffness, rotational mass and safety. While conventional alloy wheels often involve a compromise between strength and weight, 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 results in a directly noticeable advantage in acceleration, braking distance, steering precision and grip.
The BST GT TEK is not only functional, but has also received prestigious recognition: at the SEMA Show 2021, this wheel won the award for “Best New Product in the Wheel and Related Products”. It thereby officially joined the rare category of ultra-light automotive components – a class in which hardly any other street-legal wheels exist.
BST uses only high-quality carbon fiber structures sourced from the same supply chains as the aerospace industry. Every 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. Each wheel features 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 on the Porsche 991 GT market means that 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.
Made with Formula 1 technology
Every Tuff TEK wheel is produced using the same technologies found in aerospace and top-level motorsport. The wheels are ISO 9001:2015 certified and individually tested and registered with a unique serial number. Thanks to hollow spokes and advanced composite layers, they can withstand intense forces and extreme conditions — whether on the road or on the trail.
Durable, but not brittle
Carbon is not only light, but also tough. The wheels withstand temperature fluctuations, chemical influences and mechanical impact. Thanks to the epoxy finish, minor damage can often be repaired without structural damage. A long-term investment — for those who take their Jeep seriously.
Q&A – Frequently asked questions
Does this set fit directly on my Jeep Wrangler JK?
Yes, with the included adapter set, the wheels fit Wrangler JK models from 2007 to 2018 with the original 5 x 127 hub and M14 x 1.5 wheel bolts.
Do I need spacers or additional modifications?
The set is supplied with matching spacers/adapters. No further modifications are required. The wheel bolts and hub fit remain in accordance with OEM specifications.
Can I continue using my original TPMS sensors?
Yes. Jeep Wrangler JK models are equipped with TPMS, and these sensors can simply be transferred to the BST wheels.
Is this wheel set suitable for intensive off-road use?
Absolutely. With a load rating of 862 kg per wheel, this set can withstand heavy loads and rough terrain.
Can I choose from multiple finishes?
Yes, the BST GT TEK wheels can be customized according to your preferences 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, an exclusive Forged Carbon finish is also available – recognizable by its marbled appearance with more organic lines.
In terms of surface finish, three options are available: 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, so the structure of the carbon weave remains clearly visible while adding extra depth and an attractive color.
Custom colors are also available, of course. Contact us if your desired color is not listed here; almost anything is possible.
Is this street legal?
Yes. The wheels comply with the DOT E and JWL standards and are legal for road use in Europe and the United States.

Whether you enjoy rock crawling, crossing the Alps or are simply looking for the ultimate combination of appearance and performance — this BST Tuff TEK 20-inch wheel set is the most advanced upgrade you can give your Jeep Wrangler JK.
