FAQ

Are these made from real carbon fiber or just overlays?

All of our products are full carbon fiber. Each product listing specifies the construction material, and we only source high-quality parts that are tested for durability and built to meet or exceed OEM standards.

How long does shipping take and where are orders shipped from?

Shipping times vary by location. U.S. orders typically arrive within 5–7 business days, international orders within 7–16 business days, and made-to-order items may take 1–3 weeks. Full delivery details are provided in your confirmation email. For any questions, reach us at aurenzioservice@gmail.com.

Do I need a professional to install, or can I do it myself?

Many of our parts are designed for simple bolt-on installation and can be done at home with basic tools. For more complex items, such as aero kits or performance components, we recommend professional installation to ensure the best fit and results. Each product page includes installation notes and difficulty levels.

Are your parts tested for quality and durability?

Yes — every product goes through strict quality checks and is either TUV-certified, ISO-certified, or tested by our in-house team and trusted installers. We only offer parts we’d confidently run on our own cars.

What if the product doesn’t fit?

We offer easy, hassle-free returns within 14 days of delivery. If the fitment issue is on our end, we’ll cover return shipping. For other cases, exchanges are simple. Full details can be found in our Returns & Warranty Policy
