Upgrade your BMW’s stopping power with premium back-axle performance rotors for the 325d (2011, 300 mm). If you want sharper bite, cooler running and fade-resistant braking for fast-road or occasional track use, these vented 300 mm rear discs deliver the dependable feel and durability enthusiasts demand.
Engineered from OE-spec castings and finished to a precision surface for ultra-smooth contact, these rear rotors are heat treated and stress relieved for strength, helping reduce the risk of warping and vibration under heavy use. The final ground finish gives rapid bed-in, consistent pedal feel and confident braking in all conditions.
- Position: rear axle brake rotors
- Diameter: 300 mm
- Construction: vented for improved heat management
- High-precision ground finish for a perfectly level braking face
- Stress-relieved and heat treated for strength and stability
- Based on OE specifications with road-legal approvals on many applications
Choose your preferred performance pattern
- Radial-groove design often recognised as the most aggressive cooling and de-gassing layout. Multiple grooves promote a turbine effect that helps the disc run cooler, reducing fade and minimising judder.
- Curved-groove design ideal for fast-road and track-day use. Fewer, arched grooves strike a perfect balance between heat dissipation and structural strength.
- Drilled and grooved design with fully drilled, countersunk holes to vent gases that cause fade, plus straight grooves to keep pads from glazing for crisp, repeatable braking.
Why enthusiasts choose these 300 mm rear discs
- Cooler running on spirited drives and track sessions
- Improved bite and modulation with reduced fade
- Quicker bed-in thanks to a finely ground braking surface
- Stable, confidence-inspiring performance under repeated heavy stops
Pair these rotors with matching high-performance pads for the best results on the road or at the circuit. We run these on our own builds and customer cars, and feedback has been superb for consistency, durability and pedal feel.
