Elevate the look and road presence of your F97 and F98 with premium carbon side extensions from 3DDesign. Crafted from authentic CFRP with a 2x2 twill weave, these sill extensions deliver a sharper profile, purposeful aero along the flanks and a factory-plus finish that complements BMW M body lines. This is the sleek styling upgrade enthusiasts choose when they want a motorsport-inspired aesthetic without compromise.
Why this upgrade
- Vehicle-specific design for the 2019 onwards F97 and F98 platforms for a tailored, precise fit
- Authentic carbon fibre reinforced plastic with consistent 2x2 twill weave for a premium appearance
- Lightweight and rigid construction that enhances the stance and side profile
- Complements other aero pieces such as front lips and rear diffusers for a cohesive look
- Transforms the visual width and lowers the side view for a more aggressive, performance-focused style
