Dry Carbon Fiber Rear Trunk Spoiler for 2018–2021 BMW 8 Series G16 / F93 M8 Gran Coupe (3D Style)
The BMW 8 Series G16 Gran Coupe (2019–2024) is the four-door fastback Gran Coupe body variant of the G14/G15/G16 8 Series family — a full-size performance Gran Coupe on BMW's CLAR platform, spanning engine variants from the 840i through the M850i xDrive and the dedicated F93 M8 Gran Coupe. The G16 Gran Coupe's rear trunk lid is a wide, swept-back fastback panel terminating in a clean trailing edge — characteristic of the Gran Coupe body's long, low rear profile. The F93 M8 Gran Coupe shares the same trunk lid panel as the G16 standard Gran Coupe, making this spoiler correct for both the G16 (840i/M850i) and F93 (M8/M8 Competition Gran Coupe). This rear trunk spoiler is manufactured in Dry Carbon Fiber (autoclave-cured Prepreg) in a 3D-profile design — a raised, three-dimensionally contoured carbon lip at the G16/F93 trunk trailing edge. Tape-on, 2 kg, under 20 minutes.
- Fits: BMW G16 8 Series Gran Coupe (840i / 840i xDrive / 840d / M850i xDrive) and F93 M8 Gran Coupe / M8 Competition Gran Coupe — 2018–2021
- Does NOT fit: BMW G14 8 Series Coupe (2-Door) — the G14 Coupe has a different shorter trunk lid geometry. Different body, different trailing edge surface
- Does NOT fit: BMW G15 8 Series Convertible — soft-top body with a different rear deck structure
- Does NOT fit: BMW F91 M8 Coupe or F92 M8 Convertible — F91 and F92 are the Coupe and Convertible M8 variants with different rear body structures from the F93 M8 Gran Coupe

Dry Carbon vs Standard Wet-Lay — Why Dry Carbon at $373.99
Dry Carbon Fiber (autoclave Prepreg) is manufactured using pre-impregnated carbon cloth cured in an autoclave under heat and high pressure — typically 80–120 psi — rather than ambient-temperature wet-lay. Autoclave curing achieves a fiber volume fraction significantly higher than standard wet-lay carbon (wet-lay: 50–60%; autoclave Prepreg: 60–70%+), producing a lighter, stiffer part with lower void content and a more consistent surface finish. For a 2 kg rear trunk spoiler, Dry Carbon means measurably lighter and stiffer per unit weight than a wet-lay equivalent at the same geometry. BMW M Performance's G16/F93 carbon exterior accessories are Prepreg-cured — the same manufacturing specification, validating Dry Carbon as the correct standard for an 8 Series Gran Coupe trunk spoiler at this level.
3D Style Profile — Three-Dimensional Contoured Trailing Edge
This spoiler features a 3D Style profile: a raised, three-dimensionally contoured surface — raised centre section with swept lateral sections following the G16/F93 Gran Coupe trunk trailing edge curvature. The 3D profile creates a more pronounced rear visual signature than a flat lip spoiler while maintaining the Gran Coupe's broad sweeping rear profile. BMW M Performance's G16/F93 accessories include rear trunk spoilers in this 3D profile geometry — factory reference for this spoiler shape on the G16/F93 platform.
G16 (840i/M850i) and F93 (M8/M8 Competition) — Same Trunk Lid, Both Confirmed
The G16 8 Series Gran Coupe and F93 M8 Gran Coupe share the same rear trunk lid panel. This spoiler fits both: G16 840i, G16 840i xDrive, G16 840d, G16 M850i xDrive, F93 M8 Gran Coupe (600 hp), and F93 M8 Competition Gran Coupe (625 hp) — all confirmed fitment across 2018–2021.

Ordered the BMW front bumper fog light grille and the fitment was absolutely perfect. Gloss black finish looks factory-fresh and the quality is outstanding. Installation took about 30 minutes — no drilling required. Highly recommend AlchemyRide!

Fast shipping, great packaging, and the part arrived in perfect condition. The grille fits my F23 like a glove — exactly as described. Customer service was also super responsive when I had a fitment question. Will definitely order again.

I've bought aftermarket parts from many stores but AlchemyRide stands out for quality and value. The part was well-made, fit perfectly, and the price was very competitive. My BMW looks aggressive and clean — exactly what I wanted.
