SEAT Leon FR Mk3 Rear Side Splitters

Rear side splitters are one of those subtle exterior mods that make a big difference to how your SEAT Leon FR Mk3 looks and feels. Mounted at the back of the side skirts, they visually extend the rear bumper line, giving the car a wider, more planted stance that suits both road and track-focused builds. Paired with a rear diffuser or full body kit, they help tie the whole back end together so the styling looks intentional rather than pieced together.

From a performance point of view you are not gaining huge amounts of downforce, but a well-designed set of rear side splitters can help tidy up airflow around the rear corners, especially at higher speeds. More importantly, they protect the lower edges of the bumper and side skirt from road debris, kerbs, and general day-to-day abuse. That means you keep your fresh paint and expensive aero parts looking sharp for longer.

The parts we list are chosen for proper fitment on the SEAT Leon FR Mk3, using materials like ABS plastic, composite or lightweight metal that can handle daily driving without warping or cracking easily. Most upgrades are designed as direct replacements or simple bolt-on additions, so you can install them at home with basic tools or have your local workshop fit them without drama. If you are already running lowering springs, coilovers or wider wheels, rear side splitters are a smart finishing touch that completes the aggressive look and makes the whole car look lower and more purposeful.
