Project Mu SCR rotors are available as front and rear replacements including vehicles with the factory Brembo calipers. They are manufactured from the factory featuring a slotted and dimpled surface to facilitate better pad wear and maximize cooling and braking performance. SCR rotors also feature a specially designed internal vane to improve heat dissipation from the rotors. SCR rotors are developed from super tough FC Cast Iron Material and are heat-treated for reliability, durability and thermal stability under aggressive driving. To maximize street and sports driving, Project Mu is the number one choice in braking technology and performance.
