Product Description

The EBC USR1002 is part of EBC's Ultimax USR performance rotor range, 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 brake pad surface while efficiently venting gases, dust, and water during braking.

Manufactured from high-grade G3000 cast iron and precision-machined in the UK, these rotors offer strong durability and reliable heat management under both daily driving and spirited conditions. The Geomet corrosion-resistant coating helps maintain long-term protection against rust and surface degradation.

This rotor set is commonly used on BMW E46 3 Series and E85/E86 Z4 platforms, including 330i and 3.0i variants. It provides a direct OE replacement upgrade, improving pedal feel, braking response, and overall stopping confidence when paired with compatible performance brake pads.
