Heads-up on cancellations & returns: if you cancel an order or return an item, you won't get back 100% of what you paid. We apply a 10% restocking fee, the outbound shipping is non-refundable, and we have to pass on Shopify / PayPal payment processing fees; these aren't returned to us when we refund you. International orders also lose on exchange-rate spread in both directions. If the original packaging is damaged or missing, a reboxing charge applies. For international orders specifically, if you refuse to pay our shipping invoice or supply a prepaid label after placing the order, the same deductions apply. We're upfront about this — please be sure of your purchase before ordering.

Official BMW 8 Series and M8 Carbon Sill Extensions - Pair
Transform the side profile of your G14, G15, F91 or F92 with these factory-authentic carbon sill extensions. Manufactured by BMW from premium hand-made carbon fibre, this left and right set delivers the crisp, motorsport-inspired look enthusiasts want, with a precise, original-equipment fit and a finish that integrates cleanly with the car’s body lines. The result is a longer, lower visual stance and serious road presence.
As an OEM solution, these carbon rocker trims offer the quality, alignment and durability you expect from a genuine BMW upgrade. We have installed these on customer cars and on our own builds, and feedback has been consistently outstanding for fitment, appearance and overall impact.
