The Brembo GT front big brake kit for 1999–2005 BMW 330i (excluding xDrive) pairs six-piston cast calipers with 355 x 32 mm two-piece slotted rotors in Type-3 black. As a front axle direct-replacement kit, it upgrades rotor size and caliper architecture to deliver firmer brake control and improved heat handling compared with factory hardware on the specified 330i models.
