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.

Race-inspired rear styling for BMW 1 Series M140i and M135i LCI owners who want a serious visual upgrade.
Give the back end of your F20 or F21 a purposeful motorsport look with this performance styling package featuring a Formula-style centre lamp and matching lower bumper diffuser. The triangular LED centre light offers two selectable modes for the stop lamp function, with either a pulsing effect or steady illumination, and includes a rain lamp function for that unmistakable track vibe. The diffuser lines up cleanly thanks to the supplied angled alignment piece, so the fins sit just right for a factory-quality finish.
