Product Details

• Article Number: 09.B570.1X — Brembo Xtra series front axle brake disc, a sport-performance upgrade over the standard Prime variant. Direct OEM-equivalent replacement for BMW part numbers 34106787490 and 34106879122, engineered to exceed standard OE braking performance.
• Brake Disc Type: Perforated and vented — the disc features drilled holes across the friction surface combined with internal venting between the two disc faces. The perforations allow hot gases to escape during braking, improve wet weather performance by clearing water faster off the contact surface, and reduce overall disc temperature under sustained use.
• Drilled: Yes — the drilled holes are a defining feature of the Xtra line, contributing to a sportier, more responsive feel underfoot and slightly reduced unsprung weight compared to a solid vented disc.
• Dimensions: 328 mm diameter × 28 mm thickness, with a minimum wear thickness of 26.6 mm and an overall height of 73 mm. Matches factory fitment for the BMW X3 (F25) and X4 (F26) front axle.
• Bolt Pattern: 5-hole configuration with a 75 mm centering diameter. Tightening torque rated at 140 Nm for secure fitment.
• Surface Finish: Coated — protective anti-corrosion coating applied to the hub and non-friction surfaces, preventing rust buildup and maintaining a clean appearance over time.
• Machining: High-carbon — manufactured with a high-carbon cast iron composition for improved vibration damping, quieter operation, and better resistance to thermal cracking compared to standard untreated discs.
• Supplementary Info: Supplied with bolts and screws for straightforward installation.
• Vehicle Compatibility: Designed for the BMW X3 (F25, 2010 onwards) and BMW X4 (F26, 2014 onwards). Always verify against your vehicle's VIN or existing part number before purchasing.
