BMW 840Ci Brake Disc

• 5 lugs
• 12.76 in. disc diameter

• Manufactured to OE specifications using high tensile strength G3000 gray cast iron
• Precision machined, balanced, and 100 percent one by one run out inspected to guarantee zero rotor distortion out of the box

• 5 x 120 mm bolt pattern
• 324 mm disc diameter
• 15 mm bolt size
• 10.4 mm minimum thickness

• Manufactured to meet QS and ISO quality system standards
• Utilizes an electrocoating finish that provides long lasting corrosion protection
• Designed to withstand 400 hours of salt water exposure without rusting
• Double disc grinding ensures parallelism, eliminates run out, and provides near perfect disc thickness
• The double disc grinding also leaves a non-directional finish on the friction surface area for more effective pad-disc break in while providing quieter and smoother stops
• Center-split core casting offers proper heat transfer and thermal efficiency for superior braking and safety
• 100 percent fully machined hat delivers better disc balance
• Mill-corrected to a tolerance of less than 2 oz. per inch

A high quality, OE replacement brake disc. This REPLACEMENT brake disc is made from premium material for optimum disc wear and manufactured to OE comparable design, fit and specifications for balance and reliability.
