Product Details

The DFC GEOSPEC rotor line is engineered to match OEM specifications and is machined to tight tolerances for consistent fit and finish. Each rotor is inspected for critical dimensions, and vented rotors are balanced as needed before final quality checks. The coated surface helps resist rust better than conventional paint or zinc finishes, while the dry packaging eliminates the need to clean oil from the rotor before installation. The 5000 Advanced pads are formulated for stable friction performance and reduced initial break-in, making this kit a practical choice for rear brake service on the Lexus RX350, RX350L, RX450h, and RX450hL.

What This Kit Helps Address

• Rear brake noise during stopping
• Rotor rust and surface corrosion
• Uneven pad bedding after brake service
• Brake vibration caused by worn rear rotors
• Reduced stopping performance from worn pads
