We can ship to virtually any address in the world. Note that there are restrictions on some products, and some products cannot be shipped to international destinations.
When you place an order, we will estimate shipping and delivery dates for you based on the availability of your items and the shipping options you choose. Depending on the shipping provider you choose, shipping date estimates may appear on the shipping quotes page.

Elevate the aggressive stance and track-ready aesthetic of your BMW M4 with the CMST Widebody Wheel Arches. Designed specifically for the BMW G82 M4, these precision-engineered arches dramatically widen the vehicle's profile, creating space for larger, more performance-oriented wheels and tires while enhancing aerodynamic presence. This premium upgrade from CMST transforms the vehicle's silhouette into a more muscular and purposeful form.
Crafted from pre-preg carbon fiber using vacuum-bagging techniques for optimal resin distribution and structural integrity, these arches offer exceptional strength and a lightweight finish. The standard carbon fiber option features a pristine 3k 2x2 weave protected by a high-gloss UV-resistant clearcoat. For a custom painted look, CMST also offers an FRP (Fiber Reinforced Polymer) version, which arrives in a primed white finish ready for sanding and painting to match your exact vehicle specification.
Supplied by AME Motorsport, your assurance of premium quality and fitment for your BMW M4 G82.
You may return most new, unopened items within 30 days of delivery for a full refund. We'll also pay the return shipping costs if the return is a result of our error (you received an incorrect or defective item, etc.).
You should expect to receive your refund within four weeks of giving your package to the return shipper, however, in many cases you will receive a refund more quickly. This time period includes the transit time for us to receive your return from the shipper (5 to 10 business days), the time it takes us to process your return once we receive it (3 to 5 business days), and the time it takes your bank to process our refund request (5 to 10 business days).
If you need to return an item, simply login to your account, view the order using the "Complete Orders" link under the My Account menu and click the Return Item(s) button. We'll notify you via e-mail of your refund once we've received and processed the returned item.
