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.

Transform the rear of your BMW 4 Series with this CT Carbon BLAK range piano black rear valance. Designed for the F32 Coupe, F33 Convertible and F36 Gran Coupe platforms, this high gloss rear bumper insert delivers an OEM+ look with a sharper, sportier stance and a premium shine that ties in perfectly with Shadowline trim and other black styling upgrades.

Engineered for models with a dual-tip outlet on the left side, this sleek rear skirt replaces the lower bumper trim to create a clean, performance-focused finish. The deep gloss black surface gives a factory-style appearance while adding a more aggressive rear profile. We fit these regularly and our customers love the fit and finish, praising the quality, the precise lines and the instant visual upgrade.
