Product Description

This SHW Performance BRL42833 rotor is specifically engineered as a high-quality rear-left upgrade for the BMW Z4 3.2 L (E85/E86, 2005-08). With a 328 mm diameter and 20 mm thickness, it matches OEM geometry while offering enhanced materials and construction designed for higher thermal loads and improved braking feel.

The cross-drilled, internally-vented two-piece design enables better heat evacuation, improves pad contact, and helps maintain consistent braking performance under spirited driving or light track use. The high-carbon cast iron friction ring ensures strength and resistance to cracking under load, while the corrosion-resistant coating on non-friction surfaces helps maintain durability in everyday conditions.

Installation is straightforward: remove the factory rear-left rotor, clean the hub surface, install this rotor with factory hardware and torque specifications, then properly bed-in the pads. Ideal for drivers wanting enhanced braking performance with OEM-level fitment, this rotor is a strong choice for performance-oriented Z4 owners. Note: service beyond 2008 and 2025 coverage is unconfirmed.
