Shipping Policy

At Exotics Carbon Design, we take pride in crafting high-quality, made-to-order carbon fiber parts for sport and exotic vehicles. Before shipment, each custom part is subjected to a multi-point inspection as the final step in our detailed production process, ensuring it reflects our commitment to superior quality.

Most carbon fiber parts are made to order and shipped directly from our manufacturing facility. Production and delivery typically take 2-3 weeks and longer in rare cases, depending on the complexity of the part. This timeframe is an estimate and includes both production and transit time.

By placing an order, you acknowledge and agree to this processing timeframe. Smaller cosmetic components, such as mirror caps, badges, or trim pieces, may ship faster, generally within 7-14 business days, depending on stock and production flow.

If you have any questions regarding your order or shipping status, please contact us at info@exoticscarbondesign.com. Our team is committed to providing timely updates and premium support throughout the shipping process.

Material

At Exotics Carbon Design, we use only pre-preg (pre-impregnated) carbon fiber sheets—the same advanced material trusted in Formula 1, aerospace engineering, and hypercar manufacturing.

Through high-temperature autoclave curing, every component is reinforced under extreme pressure, eliminating air pockets and ensuring a flawless, uniform weave. This process guarantees a deep, glossy finish that resists fading, yellowing, and warping even under the most demanding conditions.

Each product undergoes a strict 3-stage quality control inspection before leaving our facility. Unlike many aftermarket brands, we never compromise by using fiberglass blends, resin pooling, or wet layup shortcuts. Every part we deliver reflects the highest level of motorsport-grade craftsmanship.

Just installed the carbon fiber exhaust shield cover on my McLaren 720S and I’m beyond impressed. The craftsmanship is top-tier, the weave is flawless. The only negative side is it took 8 days more to arrive but that’s fine.
