Bring smooth, quiet stopping power back to your BMW's front brakes with the Wagner Brake Front Disc Brake Rotor BD126234E. This vented, full-cast front rotor drops in as a direct-fit replacement for the 1999-2000 BMW 328i, 2001-2006 BMW 330Ci, 2001-2005 BMW 330i, 2001-2005 BMW 330xi, and 2007-2008 BMW Z4 (all engines). It measures 324.8 mm (12.788 in) outside diameter with a 24.8 mm (0.980 in) nominal thickness.
- OE-style design: engineered to match OE requirements and designed to help restore like-new braking performance.
- Resists corrosion: painted edges and hats provide corrosion resistance.
- Precision finish: a precision-ground surface requires less pad break-in time and aids proper bedding, for reliable performance, noise reduction and heat dissipation.
- Vented for cooling: application-specific OE vane design and thickness help control noise, vibration and harshness (NVH), while precision machining limits vibration for improved stability, control and reduced pad wear.
High-grade metallurgy supports structural integrity and heat dispersion. Front applications use two rotors; this listing is for one, sold individually, so replacing both sides together as a matched pair is recommended for even, balanced braking. Pair with Wagner brake pads for the intended combination. Country of origin: China.

Is this a vented rotor?
Yes. It's a full-cast, vented rotor with an application-specific OE vane design and thickness that help manage heat and control noise, vibration and harshness.
How many rotors do I need?
Front applications use two. This listing is for one rotor sold individually; replacing both sides together as a matched pair is recommended for even, balanced braking.
Does this rotor resist rust?
Yes. The painted edges and hats provide corrosion resistance.
Will it need break-in?
The precision-ground finish requires less pad break-in time and aids proper bedding. Follow your brake pad manufacturer's recommended bedding procedure.
