The relationship between General Motors and Italian brake supplier Brembo can be described as extensive. Today alone, you can find Brembo high-performance calipers on cars like the Corvette ZR1 and Z06, Buick Regal GS, Cadillac CTS-V, Chevy Camaro SS and soon-to-be ZL1. Adding to the roster will be both the all-new Cadillac XTS and ATS models, but with a twist, as they will receive the first batch of American-made Brembo brakes. They will come from a plant in Homer, Michigan.
When they hit the market, the ATS and XTS will be fitted with four-piston, two-piece aluminum calipers that were purpose-built not only for the stopping power Brembo has become known for, but for weight savings and drag reduction as well. They will have a black anodized hue on the base XTS and ATS, while the XTS Platinum will feature solid black calipers. Both the Brembo and Cadillac logos will grace the equipment as well.
