Weds Sport Unveils Japan’s First All‑Carbon Fiber Wheels – Performance, Cost & Durability

Update 2/23/10: For another all‑carbon fiber wheel, check out the one we wrote about from Carbon Revolution.

A Japanese manufacturer, Weds Sport, introduced the world’s first full carbon‑fiber wheel at the 2007 Tokyo Auto Salon. The unveiling was part of their “Dry Carbon Wheel Project,” showcasing a radical shift in wheel design and material science.

Each wheel weighs only 2.76 kg (≈6.08 lb), a remarkable reduction compared to typical forged aluminum sets that often exceed 8 kg. The lightweight construction offers instant torque response and improved handling, especially on high‑performance vehicles.

In terms of cost, a complete set of Weds Sport’s carbon‑fiber wheels is priced at roughly $10,000–$12,000. While this may seem steep, it aligns with premium aftermarket options such as HRE’s custom forged wheels, which can cost over $8,000.

During the Tokyo Auto Salon display, a side‑by‑side comparison was offered. One wheel featured a carbon‑fiber face over a forged aluminum rim—an approach that blends the visual appeal of carbon with the proven strength of aluminum. This hybrid option is often more affordable while still delivering a striking look.

Questions about durability naturally arise with a 100 % carbon‑fiber wheel. Experts note that while carbon is strong in tension and compression, it can be more susceptible to impact damage than metal. Repair options are limited; a significant crack usually requires a full replacement. For racing or high‑mph street use, many recommend a hybrid design or a robust hub material—such as the magnesium hubs used by Dymag—to enhance structural integrity.

We’d love to hear from enthusiasts who’ve tested these wheels in real‑world conditions. Share your experiences or ask questions in the comments below.
