Featuring a vented rotor design with straight vanes, these rotors promote optimal airflow to dissipate heat generated during braking. The slotted surface helps to evacuate gases, dust, and debris from the brake pad surface, improving pad contact and reducing brake fade during aggressive driving or track use.\u003c\/p\u003e\u003cp\u003eThe rotor’s hat is coated to resist corrosion, extending the service life and maintaining appearance. The floating disc mounting design allows for controlled thermal expansion, reducing the risk of warping under high temperature conditions. With a nominal thickness of 24.0 mm and a discard thickness of 22.4 mm, these rotors provide a durable and reliable braking surface. The 5-lug hole pattern with a 120 mm bolt circle diameter ensures proper fitment on compatible BMW models.\u003c\/p\u003e\u003ch2\u003eStopTech Sport Slotted Disc Brake Rotors Product Line\u003c\/h2\u003e\u003cp\u003eThe StopTech Sport Slotted Disc Brake Rotors line is designed for drivers seeking improved braking performance without compromising OEM fitment. This product line focuses on enhanced heat dissipation and consistent braking feel through features like slotted surfaces and vented rotor construction.
