Transform your G83 M4 cabriolet with a premium CFRP aero package engineered for the 2021 onward platform. This CT performance styling pack uses ultra-lightweight prepreg dry carbon for a true motorsport look and feel, delivering sharper aesthetics and real-world weight savings without compromising everyday usability.
We run this upgrade on our own demonstrators and customer cars at MJ Modifications. Fit and finish are superb, with consistent weave alignment and an aggressive OEM plus appearance that elevates your 4 Series M to a new level.
What you get
- Front lip spoiler - a low-profile bumper extension that sharpens the nose and improves front-end presence
- Side skirt blades - rocker panel extensions that visually lower the car and tie the profile together
- Rear diffuser with bumper corner trims - a sculpted lower valance for a wider, more purposeful rear stance
- Boot lip spoiler - subtle tailgate wing for a clean, performance-led finish
Why choose dry carbon prepreg
- CFRP construction - autoclave-cured for high stiffness-to-weight and crisp definition
- Ultra-lightweight - meaningful mass reduction versus GRP or ABS alternatives
- Premium weave - uniform pattern for a cohesive, factory-style aesthetic
- Track-inspired styling - enhanced aero presence with everyday durability
