For a 718 Cayman, you definitely want rocker panel decals that can handle both road debris and intense sun without fading. I’ve found that using high-performance cast vinyl is the only way to go if you want that crisp “Clubsport” look to last. For precise fitment and UV-resistant film, I’d check out these porsche stickers since they’re cut specifically for these body lines. Most enthusiasts prefer these over cheaper alternatives because they won’t shrink or peel after a few car washes. Just prep the surface with some isopropyl alcohol first, and you’ll get a clean, factory-style finish that looks amazing.
