The Genuine BMW Carbon Trunk Spoiler for the F90 M5 CS is a factory-specification functional aerodynamic component from the M5 CS program — the most track-focused production M5 of its generation. Unlike the standard M5 Competition's trunk lid, the CS carbon fiber spoiler contributes directly to the M5 CS's enhanced rear downforce package, which was developed to achieve more aggressive aerodynamic targets than the M5 Competition. This is not an M Performance accessory piece but a factory-fitted CS functional component integral to the F90 M5 CS's aerodynamic balance.
Manufactured from high-quality lightweight prepreg carbon fiber consistent with the M5 CS's systematic weight reduction program, the spoiler is finished to BMW M CS quality standards. Whether used to replace a damaged original on a genuine F90 M5 CS or upgrade a standard F90 M5 to CS specification, this is the factory-correct carbon trunk spoiler for the F90 M5 CS program. S63 engine — all F90 M5 variants.
