Check My VINA carbon front lip on its own can look like an afterthought. Side skirt extensions are what tie the front to the rear and drop the visual ride height along the whole side of the car.
- Real carbon fiber: genuine carbon construction under a clear coat, not painted plastic or a carbon look wrap.
- Lowers the whole side profile: extends the factory skirt line down, so the car reads lower without touching the suspension.
- Fits both generations: built for the F97 X3M and F98 X4M side skirts, pre LCI and LCI, 2019 and up.
- Sold as a pair: driver and passenger side included.
- Pairs with: our carbon rear diffuser, for a matched finish front to back.
Fits: BMW X3M (F97) and X4M (F98), 2019 and up, pre LCI and LCI.
Install: mounts along the factory side skirt line, no cutting. Clean and degrease the skirt first, dry fit both sides before committing, and let adhesive cure fully before washing the car. Professional install recommended on a part at this price point.
Made to order. We'll send tracking the moment it's on its way. 30 day fitment guarantee.
