The result is a rear end that reads as a factory motorsport variant rather than an accessorised road car, with far more depth and shadow than any add-on can produce.\u003c\/p\u003e\n\u003cp\u003eEvery piece is 100% dry carbon fibre in gloss black, autoclave-formed and finished so the weave runs cleanly across the complex surfaces where the strakes meet the outer sections.\u003c\/p\u003e\n\u003cp\u003eThis is the halo option in the G90 range. It costs more and takes longer to fit than a bolt-on, and it is aimed at an owner building the car properly rather than adding a detail.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003ch3\u003e100% Dry Carbon Fibre\u003c\/h3\u003e\n\u003cp\u003eGenuine dry carbon throughout with a gloss black finish, not a wet-lay or hydro-dipped imitation.\u003c\/p\u003e\n\u003ch3\u003eSQ-B Full Replacement Design\u003c\/h3\u003e\n\u003cp\u003eReplaces the lower rear section rather than mounting over it, producing far greater depth than a bolt-on diffuser.\u003c\/p\u003e\n\u003ch3\u003eMulti-Piece Sculpted Structure\u003c\/h3\u003e\n\u003cp\u003eSeparate outer sections and centre element combine into a single deep, shadowed form across the full width of the car.\u003c\/p\u003e\n\u003ch3\u003eGloss Black Finish\u003c\/h3\u003e\n\u003cp\u003eA deep gloss clear coat that holds its depth and resists yellowing.\u003c\/p\u003e\n\u003ch3\u003eMoulded to the G90 Bumper\u003c\/h3\u003e\n\u003cp\u003eFormed to the exact contour of the car so the outer edges follow the bumper line precisely.\u003c\/p\u003e\n\u003ch3\u003eThe Halo Rear Treatment\u003c\/h3\u003e\n\u003cp\u003eThe most aggressive rear option available for the platform, for a build where the rear is the focal point.\u003c\/p\u003e\n\u003ch2\u003eStyling Benefits\u003c\/h2\u003e\n\u003cp\u003e• The most dramatic rear treatment available for the G90\u003cbr\u003e• Genuine depth and shadow rather than a flat add-on panel\u003cbr\u003e• 100% dry carbon construction\u003cbr\u003e• Reads as a factory motorsport variant\u003cbr\u003e• Pairs with the SQ Style front canards for a matched kit\u003c\/p\u003e\n\u003ch2\u003eVehicle Fitment\u003c\/h2\u003e\n\u003cp\u003eBMW G90 M5 Sedan (2024+)\u003cbr\u003eBMW G99 M5 Touring (2024+)\u003c\/p\u003e\n\u003ch2\u003ePlease Note\u003c\/h2\u003e\n\u003cp\u003eProfessional installation is required.
