Real dry carbon coverage for all four corners of your S650 — widened stance, chip protection, zero drilling.
The S650's body lines beg for width, and this XL extended carbon kit delivers it without touching a drill. Each quarter-panel extension and deflector is laid up from dry pre-preg carbon fiber — the same process used on real motorsport bodywork — for a rigid, lightweight part with a deep high-gloss weave that reads as factory-plus the moment it's on the car. The extended profile pushes coverage further than a standard deflector, visually lowering and widening the Mustang while shielding your paint from the rocks, road debris, and water that chew up quarter panels.
Fitment is vehicle-specific, not universal. The extensions snap onto the factory contours, the deflectors bolt on through OEM screw locations, and automotive-grade double-sided tape seals every contact surface for a clean, rattle-free fit. Nothing is permanent — pull the tape for maintenance and your panels are untouched, no holes, no damage. Run it Front Only, Rear Only, or grab the full Front & Rear set to do all four corners at once and tie the whole build together.
Autoclave-grade dry carbon fiber for true rigidity, low weight, and a deep woven gloss that holds up over time — not a glossed-over fiberglass shell.
Reaches further across the front and rear wheel areas than a standard deflector, deflecting debris and water while widening the car's planted stance.
Full kit includes front fender extensions, front deflectors, rear fender extensions, and rear deflectors — left and right for every corner.
Precision-molded to factory body lines and mounting points for a tight OEM-plus look with no gaps or misalignment.
Snap-on extensions plus bolt-on deflectors using OEM screws. Double-sided tape seals the surface and lifts off clean for maintenance — zero holes.
Ships with all the screws and tape needed for a secure, straightforward install on every panel.
