passing the info along. I ordered up set from them and was told they developed a limited number of 2 piece modular race rotors for several road course/ SCCA type teams and have a few sets left over for our stangs. They were pricey, but supposedly they are serious hard core rotors designed for abuse and longevity. slotted/drilled and can be turned as well unlike most. anyway if anyone is interested in a brake upgrade from the Brembo rotors !. they look killer outta the box!
