The R1 Concepts WGPN1-27025 eLine Series Disc Brake Kit delivers OE-level braking performance with added durability for everyday street driving. This kit includes two high-performance brake rotors machined from G3000/G11H18 grade cast iron and finished with a silver rust-protective coating, keeping corrosion at bay and your brakes looking clean.
