The drilled and slotted surface pattern enhances water and debris evacuation, while the vented rotor construction supports consistent braking performance. This product line is tailored for vehicles requiring reliable stopping power and rotor longevity, such as the Land Rover Range Rover and Range Rover Sport.\u003c\/p\u003e\u003ch2\u003eTechnical Description and Specifications\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor features a vented design that promotes airflow to reduce heat buildup during braking. The directional surface is both drilled and slotted, which helps maintain clean pad contact and improves braking response. The rotor has a nominal thickness of 34 mm and a discard thickness of 31 mm, ensuring a clear service life indicator. The rotor’s outside diameter measures 380 mm, with an overall height of 62.1 mm. The hat section is finished in Geospec silver grey and includes a rust-resistant coating to protect against corrosion. The rotor mounts with five 15 mm diameter bolt holes arranged on a 120 mm bolt circle diameter, compatible with the specified Land Rover models.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRestores braking performance on Land Rover Range Rover and Range Rover Sport vehicles\u003c\/li\u003e\n\u003cli\u003eReduces brake fade during heavy or repeated braking\u003c\/li\u003e\n\u003cli\u003eImproves heat dissipation to extend rotor and pad life\u003c\/li\u003e\n\u003cli\u003eMinimizes water and debris buildup on the rotor surface\u003c\/li\u003e\n\u003cli\u003ePrevents rust and corrosion for longer service intervals\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor is installed with the directional surface oriented correctly according to the vehicle’s rotation. Verify bolt hole alignment with the 5-lug pattern and 120 mm bolt circle diameter. Check rotor thickness before installation to confirm it meets or exceeds the discard thickness of 31 mm. Clean the rotor surface to remove any protective coatings or residues prior to mounting. Proper torque specifications should be followed for all fasteners.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures the 830-11021L rotor to meet OEM standards for fitment and performance on Land Rover Range Rover and Range Rover Sport models.
