Is your carbon fiber real?

All of our products are made from genuine carbon fiber, not hydro-dipped or vinyl wrapped. We source high-quality materials for each piece, and every product is constructed using industry-standard methods including dry carbon for specific high-performance applications. No corners are cut. No filler materials.

Absolutely not. None of our products are drop shipped. Every item is manufactured at our dedicated facility and shipped to our Chicago-based warehouse, where it undergoes a full inspection and quality control process before being delivered to you. We also offer a selection of custom designs created in-house that are exclusive to Insignist Motorsports — ensuring you're not just getting generic parts passed from one supplier to another.

What’s the difference between dry carbon and regular carbon fiber? Why is dry carbon more expensive?

Dry carbon fiber is lighter, stronger, and significantly more expensive to produce than wet (gloss) carbon. While wet carbon is layered with resin and cured with a gel coat for aesthetics, dry carbon is cured under vacuum pressure in an autoclave — the same process used for Formula 1, aerospace, and race-spec builds. This makes it the premium choice for anyone who prioritizes performance, weight savings, and structural integrity.

Is everything on your site in stock?

All of our products are always available to order, a lot are in stock and others are crafted to order, entering production shortly after your purchase. Because we’re a growing business, we balance warehouse space and customer demand, so some orders may take a little longer to fulfill. That said, we maintain an 'In-Stock & Ready-to-Ship' section, clearly displayed on our homepage and in the navigation menu. You can filter by BMW model and instantly view parts ready to ship from Chicago. We’re transparent with our customers, and you can always check your order status by emailing insignist.com@gmail.com or using the Contact Us page. We typically respond within 24–48 hours.

Yes! We want you to have your item as soon as possible. Items listed in our Chicago warehouse under 'In Stock – Ready to Ship' usually ship within 1–3 business days. If it's crafted to order, it enters our tracked production queue and ships when ready. You can always request updates as your order progresses.

Do you ship to Norway?

Our checkout system currently collects VAT on all items, even those above this threshold.

Not too aggressive, not too subtle - Balanced Look

This diffuser was a great choice, real carbon, seamless look with the IMS Performance style front lip for G20. It goes well with the car if your not looking to make it look crazy, and has the perfect balanced look. Would definitely recommend, and pricing is awesome.
