It follows the roofline but does not do anything with it. The SQ design splits that span into two raised outer wings with a channel between them, so the roof reads as engineered rather than merely tapered — the same visual trick BMW uses on its own motorsport-derived cars.\u003c\/p\u003e\n\u003cp\u003eBecause it sits at the highest point of the car, this is the change that reads first in a mirror and last in a rear-three-quarter photo. On a coupe-SUV it does more per dollar than almost anything else.\u003c\/p\u003e\n\u003cp\u003eMoulded in dry carbon fibre with a gloss clear coat and formed to the exact contour of the roof, it fits over the factory panel with supplied automotive tape — no drilling into the roof skin.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003ch3\u003eDry Carbon Fibre\u003c\/h3\u003e\n\u003cp\u003eGenuine dry carbon construction with a deep gloss clear coat, lightweight where weight matters most — at the top of the car.\u003c\/p\u003e\n\u003ch3\u003eSQ Twin-Wing Design\u003c\/h3\u003e\n\u003cp\u003eTwo raised outer sections with a channel between them, rather than the factory's single soft blade.\u003c\/p\u003e\n\u003ch3\u003eMounts Above the Rear Glass\u003c\/h3\u003e\n\u003cp\u003eSits at the top of the tailgate glass, which is where the roofline actually terminates.\u003c\/p\u003e\n\u003ch3\u003eMoulded to the Roof Contour\u003c\/h3\u003e\n\u003cp\u003eFormed to the exact curve of the X4 roof, so it sits flush across its whole span.\u003c\/p\u003e\n\u003ch3\u003eTape-On Installation\u003c\/h3\u003e\n\u003cp\u003eFits over the factory panel with the supplied automotive tape.
