Used BMW 8 Series Quarter Panel

No — the G14 (convertible), G15 (coupé), and G16 (Gran Coupé) are distinct body styles on the same platform and their quarter panels are completely different pressings that will not interchange. Body style is the first question with any quarter panel, so always confirm the exact body style of both donor and recipient car before approaching a breaker. Never assume a panel fits simply because the cars share the same generation platform.

The current BMW 8 Series (G14/G15/G16) launched in 2018, and providing both cars share the same body style you are broadly looking at the same generation throughout its run into the mid-2020s. However, BMW occasionally makes mid-generation pressing changes that are not publicly documented, so confirm with the breaker using your exact registration against the donor car's registration rather than relying on build year alone. Matching body style first — coupé to coupé, convertible to convertible, Gran Coupé to Gran Coupé — is essential before anything else.

Trim level does not affect quarter panel fitment on the BMW 8 Series — the body pressing is the same whether the car is an 840i, 840d, M850i, or carries an M Sport, M Sport Pro, or Individual badge. What can differ cosmetically are any trim-specific side mouldings, vents, or badging that sit on or around the panel, so be prepared for minor cosmetic differences if the donor car is a different trim to yours. Confirm the body style and door configuration match, then fitment across trim levels should not be a barrier.

Yes — nearside (passenger side, left) and offside (driver side, right) quarter panels are mirror images of each other and are not interchangeable, so always specify NS or OS clearly when requesting a quote from a breaker. This applies across all three 8 Series body styles.

BMW issued a facelift to the 8 Series range during its production run, and although the generation platform is unchanged, whether the quarter panel pressing itself was revised at that point is not something that can be stated with certainty here. Name the exact registration of your car and the donor car when speaking to your breaker, and ask them to check the panels side by side or against their stock listings before committing — this is exactly the type of mid-generation change that is best confirmed at the breaker level rather than assumed.

No — despite BMW sharing platforms across model families, the 4 Series Gran Coupé and 6 Series are different cars with different body dimensions and completely different quarter panel pressings to the 8 Series G14/G15/G16. The quarter panel is a body-style and model-specific part, not a generic platform component. Only source a panel that is confirmed as coming from the correct 8 Series body style.
