Everything you need to know about RSI c6 carbon fiber parts.

Frequently Asked Questions

1️⃣ Are RSI c6 parts made in real carbon fiber?

Yes. Every RSI c6 component is made from 100% real carbon fiber or forged carbon, handcrafted and autoclave-cured in Italy. We never use fake carbon or overlay stickers — only genuine motorsport-grade materials.

2️⃣ What’s the difference between Carbon Fiber, Forged Carbon, and Unpaint Carbon?

  • Carbon Fiber: Classic weave pattern, available in gloss or matt finish.
  • Forged Carbon: Unique marble-like texture, bold and luxurious.
  • Unpaint Carbon: Raw carbon surface, ready for painting or custom finish.

Each option is autoclave-cured for maximum strength and minimum weight.

3️⃣ Are the parts plug & play? Do they fit the original mounts?

RSI c6 parts are handcrafted in 100% real carbon fiber, so fitment can vary depending on the product type:

  • Some parts are plug & play, designed to replace the OEM component directly.
  • Others are covers, made to be installed over the original part for an easy upgrade.
  • A few items may require minor modifications or adjustments due to the precision and handcrafted nature of carbon fiber.

All details are clearly explained in the Fitting Information section of each product page.

4️⃣ Can I request a custom finish or color?

Absolutely.

RSI c6 offers custom finishes on request — including forged carbon with gold, silver, or rose gold leaf, and personalized clear coats (gloss, matt, satin).

Just contact us before ordering to discuss your project.

5️⃣ Are these products street legal?

RSI c6 parts are made for aesthetic and performance enhancement, not structural use.

Each product comes with a material certification proving it is made from 100% real carbon fiber or forged carbon.

This document can be used by the customer to request TÜV or local approval according to their country’s regulations.

We do not provide TÜV homologation directly, as requirements vary depending on region and vehicle model.

6️⃣ How long is the production time?

Each product is handcrafted to order.

Average production time: 30–35 working days, depending on workload and finish type. Some products need additional timing.

We’ll keep you updated throughout the process until shipment.

7️⃣ How do I take care of carbon fiber parts?

Use a microfiber cloth and a non-abrasive cleaner.

Avoid harsh chemicals and high-pressure washes near exposed carbon.

For long-term gloss and UV protection, apply a light ceramic coating or wax every few months.

8️⃣ Do you ship worldwide?

Yes — RSI c6 ships worldwide.

We use insured express couriers (UPS, DHL, FedEx) with tracking and customs assistance for each destination.

9️⃣ Is VAT included in the price?

No — all prices are shown without VAT.

For UE Country: VAT will be calculated automatically at checkout based on your shipping country.

For Extra UE Country: Customs Duties will be paid to the courrier

🔟 Can I return a custom-made part?

Custom orders (specific finish or personalized details) are non-refundable, as each piece is handmade for you.

Standard parts can be returned within 14 days if unused and undamaged.
