The EBC USR slotted front rotor for 2006–2009 BMW Z4 3.0 Si delivers a sport-oriented braking upgrade with precision-machined British-made grey iron construction. USR slots are sized to reduce air noise while helping clear dust and heat, which supports cooler running and reduced fade when paired with a compatible high-friction pad. Vented design and OE-style fitment simplify replacement.
