Product Description

The EBC USR1003 is part of EBC's Ultimax USR performance rotor series, engineered to improve braking consistency, reduce noise, and enhance thermal stability compared to standard OEM brake discs. The fine-slot design helps maintain a clean pad surface while efficiently venting gases, dust, and moisture during braking.

Manufactured from high-quality G3000 cast iron and precision-machined in the UK, these rotors are designed for durability and reliable heat management under both daily driving and spirited conditions. The Geomet corrosion-resistant coating helps protect against rust and maintains long-term rotor performance.

This rear axle rotor set is commonly used on BMW E46 330i/330d and Z4 3.0i platforms. It provides a direct OE replacement upgrade that improves pedal feel, braking response, and overall stopping confidence when paired with compatible performance brake pads.
