GT4 RS

For owners, builders and motorsport teams dedicated to the Porsche 718 Cayman GT4 RS platform, our GT4 RS category delivers purpose-built composite upgrades engineered for both style and performance. We understand that every gram, every aerodynamic contour and every mounting point matters when you’re working at the limits—and our GT4 RS offering is crafted accordingly.

Our kits combine high-grade carbon fibre (2×2 weave, 240 gsm or higher), precision-machined mounting interfaces, and a fitment-first philosophy. Whether you’re upgrading aesthetic components like roof rails and hood vents or serious performance parts like diffuser panels and wing end plates, each item is designed to bolt right onto your vehicle with minimal adaptation. We match weave patterns, finish, and mounting geometry so that your upgrades integrate seamlessly with OEM components—no compromise.

On the performance side, weight savings are significant; enhanced stiffness improves aero responsiveness; and durability is tracked through motorsport-grade QA protocols. Meanwhile, our finishing processes ensure UV resistance, consistent gloss levels, and long-term aesthetic integrity. After all, when you’re track-day ready or showing at the paddock, the details matter.

Even more important: we back each part with documentation, fitment instructions, and customer support. As part of our GT4 RS series, you’ll gain access to validated mounting kits, optional finishes (weave-matched or Chevron), and tailor-made solutions to suit your build theme—be it Weissach-style, club-use or whole competition.

At Pfaff Technologies, we understand that the GT4 RS community demands more than just “look good” parts—they demand engineering commitment, motorsport heritage, and product reliability. That’s precisely what we deliver. Join the engineers, chassis specialists and teams who trust our GT4 RS upgrades for track and street alike.
