BMW F98, X4M Carbon Fibre Rear Trunk Spoiler

BMW F98 X4M Carbon Fibre Rear Trunk Spoiler

Sharpen the tail of your BMW F98 X4M with this carbon fibre rear trunk spoiler — a raised ducktail profile that lifts the trailing edge of the boot lid and finishes the coupe roofline properly.

The X4's whole shape builds toward the rear: the roof drops, the glass rakes, and then the boot lid just stops. A raised lip is what completes that line. It picks the eye up at the point the roof runs out, so the car reads as one continuous shape instead of a tall SUV with a sloped back.

The profile is a genuine ducktail — the centre rises and the ends taper down into the boot corners, so it reads as sculpted rather than as a strip stuck on the back.

Formed in carbon fibre with a gloss clear coat and moulded to the F98 boot lid, it fits over the factory panel with the supplied automotive tape. No drilling, and it comes off cleanly if the car is ever returned to standard.

Key Features

Genuine Carbon Fibre

Real carbon construction with a deep gloss clear coat, not a wrap or a printed finish.

Ducktail Profile

A raised centre that tapers into the boot corners, sculpted rather than a flat strip.

Moulded to the Boot Lid

Formed to the F98 tailgate contour so it sits flush along its whole length.

Tape-On Installation

Fits over the factory panel with the supplied automotive tape. No drilling.

Fits Every X4 Body

The tailgate did not change at the facelift, so this spoiler suits pre-LCI and LCI cars alike, and the standard X4 as well as the X4M.

The Most Affordable Change

The lowest-cost carbon addition for the X4M, and the one most visible from behind.

Styling Benefits

• Finishes the coupe roofline at the boot

Please Note

Please select your exact model above so we can confirm the correct part before dispatch.

Professional installation is recommended. The boot lid must be clean and dry, and the spoiler positioned and taped for alignment before the backing is removed — once the adhesive is down it does not move.

Allow the adhesive to cure before washing the car or using the tailgate repeatedly.

Carbon fibre is a natural woven material. Minor variation in weave pattern between pieces is characteristic of the material and not a defect.

Made to order. Please contact us to confirm current lead time before ordering.
