2024+ S650 Mustang Rear Diffuser Side Quarter Splitter Extensions

Give your S650’s hips the extra punch they deserve. Carbon Addons rear quarter splitters extend the rocker line with crisp, motorsport inspired edges and a satin black finish that looks factory but hits harder.

Highlights

• Made to match: CAD-modeled for all 2024+ EcoBoost & GT trims. No awkward gaps.

• Tough ASA construction: UV-stable, impact-resistant, and paint-ready if you want a custom pop.

• Easy Install: Each side reuses two factory push-pins and adds one self-tapping screw or push-pin (user-supplied). Just mark, drill, fasten, done.
