The R1 Concepts GEO-Carbon drilled-and-slotted sport brake kit for 2007–2015 BMW 325i front applications combines carbon-coated rotors and performance sport pads to support street and light track braking. Drilled holes and slots improve ventilation and reduce heat buildup for steadier stopping. R1 rotors are mill-balanced and made to OEM targets from G3000-grade cast iron with rust protection. Pads are a low-dust, asbestos-free formulation with shims included; kit includes hardware for installation.
