Precision Fitment

Why choose the ASM mirror covers for the BMW G20
Mirror caps are one of the first details people notice from the driver’s seat and from outside the car, which makes them one of the most effective carbon upgrades for the money. Every ASM part is checked for fit and finish before it leaves us, and is backed by our warranty and UK-based support.
Forged carbon is made from chopped carbon fibre strands pressed in a heated mould. It is light and strong, and every part has its own marble-like pattern, so no two pieces look exactly the same. Learn more about carbon types in our dry vs wet carbon guide.
Fitting and care
The original caps unclip from the mirror body and these covers clip into the same mounting tabs. Most owners fit them at home in under 30 minutes with a plastic trim tool; work slowly around the tabs and warm the mirror area slightly in cold weather. Clean carbon surfaces with a soft microfibre cloth and pH-neutral products, and protect them with a UV-stable wax or ceramic coating. Step-by-step advice: How to protect and maintain carbon fibre parts.
Delivery, returns and warranty
Every order ships from the UK with tracked delivery to the UK, Europe and worldwide. Delivery options and costs are shown at checkout and explained in our shipping policy. Unused items in original condition can be returned within 14 days, and return shipping is paid by ASM – see the refund policy. Manufacturing defects are covered by the ASM warranty.

Is fitting difficult?
No special skills are needed for most owners, but take your time. The original caps unclip from the mirror body and these covers clip into the same mounting tabs. If you prefer, any specialist or body shop can fit them quickly.
What is forged carbon?
Forged carbon uses chopped carbon strands pressed in a heated mould instead of woven sheets. It is light and strong, and its marbled pattern is unique to every part.

The questions
worth asking first
Fitment, installation, materials, lead time and support — the answers that settle the last doubts before you order. Anything not covered, the specialist line is one tap away.
Fitment is defined by the product title, the listed application scope and your platform. If you're unsure, open the WhatsApp line and a specialist will confirm the correct application before you order.
Yes — particularly for carbon aero, exhaust components and platform-specific upgrades, where alignment, finish protection and correct hardware positioning matter to the result.
It depends on the part, but the standard is consistent: disciplined finish, clean visual consistency and resolved platform-specific presentation. Pre-preg carbon and lightweight composite where the application calls for it.
It depends on whether the part is in stock or built to order. The estimated timeline on the product page is the reference to use before checkout — and the specialist line can confirm it for your exact spec.
Yes. For fitment, visual direction, material choice or build planning, use the WhatsApp block on this page and a specialist will guide you before you place the order.
Yes — worldwide shipping is available across most ASM Sports Tech lines. Method and transit time vary by product category, destination and dispatch origin.
