Carbon Fiber Side Skirt Extensions for BMW M4 G82 / G83 (2021+)
Skirt extensions that mount along the underside of the factory M4 side skirts, lowering the visual line of the car between the wheels and tying a carbon front lip and rear diffuser together into one look. They are made from carbon fiber reinforced with a glass fibre composite, finished in a high gloss lacquer, then hand and machine polished and sealed under a double-layer anti-UV clear coat for depth and protection.

Installation

- Check clearance over kerbs and ramps once fitted.
FAQ
Do these replace the factory side skirts? No. They mount onto the existing skirts as extensions.
Does it fit the M3? No. M4 G82 and G83 only.
Is drilling required? Screws are supplied alongside tape. A screwed fit is more secure but makes permanent holes.
Do they match a carbon front lip and diffuser? Yes, they are designed to be paired with M4 carbon front and rear pieces.

Ordered the BMW front bumper fog light grille and the fitment was absolutely perfect. Gloss black finish looks factory-fresh and the quality is outstanding. Installation took about 30 minutes — no drilling required. Highly recommend AlchemyRide!

Fast shipping, great packaging, and the part arrived in perfect condition. The grille fits my F23 like a glove — exactly as described. Customer service was also super responsive when I had a fitment question. Will definitely order again.

I've bought aftermarket parts from many stores but AlchemyRide stands out for quality and value. The part was well-made, fit perfectly, and the price was very competitive. My BMW looks aggressive and clean — exactly what I wanted.

Excellent product and super easy to install. The gloss black finish matches my M Sport bumpers perfectly. Shipping was faster than expected and the part was well-packaged. Very happy with my purchase — my car looks completely transformed!
