KIA Optima (K5) 2016-2020 Widebody Kit
The Wide & Wild Widebody Kit is engineered exclusively for the 2016–2020 KIA Optima (K5 JF) — the generation known for its sleek fastback profile, sculpted body lines, and upscale European‑inspired design. The JF K5 has one of the cleanest OEM shapes in the midsize segment, and this kit amplifies those lines with bold, model‑specific flares that instantly widen the stance and transform the sedan into a show‑ready, street‑aggressive build.
Perfect for stance setups, VIP‑inspired builds, and full aero transformations, this kit allows for wider wheels, lower ride heights, and a more dominant silhouette while keeping the rear doors fully functional. Molded from black ABS plastic, the panels deliver durability, heat stability, and crisp shaping ideal for daily‑driven and performance‑styled Optima builds.
