TORAYCA™ is a carbon fiber material made by Toray Industries in Japan, its the same company that supplies carbon to brands like Lamborghini, McLaren, Aston Martin, and even Ferrari. It’s the real deal used in supercars, race cars, and aerospace builds where strength, weight, and heat resistance actually matter.

We use genuine Japanese TORAYCA™ Carbon Fiber in all our wet and dry carbon parts. Why? Because it’s lighter, stronger, and more reliable than the cheap composite blends flooding the market from Aliexpress. TORAYCA™ holds up under pressure, keeps its shape over time, and doesn’t fade or fray like lower-grade alternatives.

This is the carbon you use when performance isn’t optional. If you're building a car that turns heads and doesn’t cut corners, TORAYCA™ is the standard.

And it’s the only carbon we trust.

Dry carbon fiber is the premier choice, being 70% lighter than wet carbon and constructed entirely from carbon material, providing a distinct, symmetrical weave. Wet carbon fiber, while slightly heavier, is also high quality and involves applying carbon material onto a mold. Both options offer excellent performance and aesthetic appeal.
