EBC 06-09 BMW Z4 3.0 Si GD Sport Front Rotors

If you're looking to get more out of your BMW's braking system, especially during spirited driving or when carrying extra weight, these EBC 3GD Series Sport Slotted Rotors are a solid option for the front of your 2001-2006 330Ci, 330i, 330xi, or 2006-2009 Z4. These rotors are made from OE spec grey cast iron, the same material used in new car production, and are designed to help your brakes perform better under load and at speed.

The key feature here is the sport slotting. These wide slots are designed to help sweep away dirt, dust, and debris from the braking surface, which helps reduce brake fade and keeps your pads making consistent contact. This design also helps the rotors run cooler, which is crucial for maintaining braking performance when you're pushing your car or towing. For imported vehicles like your BMW, these rotors come with a gold anodized finish for protection.

These rotors are a direct fit for the front of your specified BMW models. They are vented and measure 325mm in diameter, with a thickness of 25mm. You'll want to ensure you have the correct brake pads for these rotors; they are designed for FMSI pad number D946.
