Each Recaro Recycled Carbon Fiber Infusion shell uses, on average, between 10% and 11% of the reclaimed dry fiber instead of glass fiber strands. The materials in the shell include braided woven carbon, woven glass, and vinyl ester epoxy resin instead of polyester resin. As a company known for being first-to-market with seating technology, Recaro’s RCF Infusion works to eliminate some of the waste generated after track weekends by recycling carbon fiber that has been left behind while also increasing the strength and durability of this new racing shell through the manufacturing process. 

Mercedes 402mm Front Iron Rotor Conversion Girodisc’s 402mm front iron rotor conversion gives your Mercedes the braking consistency and durability that carbon-ceramic rotors simply can’t match. This direct bolt-on upgrade replaces the OEM carbon-ceramic setup with a lighter, more serviceable, and thermally stable iron rotor system—ideal for high-performance street driving and demanding track conditions alike.
