The StopTech drilled-and-slotted rotor for 2007–2009 BMW 328 (left front) is a one-piece direct-replacement disc that improves braking response by evacuating heat, gases and pad debris to reduce glazing and increase initial bite. Premium e-coating and advanced metallurgy protect against corrosion, lower pad squeal and resist thermal cracking. Designed for OE fitment, the drilled and slotted face also enhances wet-weather braking performance.
