BMW 1 Series E87 123d Rear Rotor Upgrade - 300 mm Vented

Give your E87 123d the stopping power it deserves with premium rear rotors engineered for fast road and track day use. These TAROX rear rotors are a direct-fit upgrade for the back axle, with a 300 mm diameter and vented construction for superb cooling, pedal feel and consistency.

Why enthusiasts choose this upgrade

• Stronger, cooler and more consistent under hard use thanks to heat treatment and precision machining
• CNC turned and then stress relieved after each machining phase for stability under temperature
• Precision ground by hand to around 0.015 mm flatness for an ultra-smooth, quiet contact surface
• OE-spec castings with TÜV pedigree, with many applications carrying TÜV and ABE approvals

Choose your preferred face design

All patterns are based on OE specifications for straightforward installation on the BMW 1 Series E87 123d rear axle.

• G88 - Multiple radial grooves create a turbine-style effect that helps shed heat and gases. Designed to minimise fade, vibration and the risk of cracking during repeated heavy stops.
• F2000 - Curved grooves balance cooling with material strength. Ideal for fast road driving and serious track sessions, helping to deglaze pads and maintain bite.
• Sport Japan - Fully drilled, countersunk holes for effective gas evacuation, paired with six grooves to keep pad faces fresh. Built for drivers who want sharp response and purposeful looks.

Benefits you can feel

• Improved bite and modulation on the rear axle
• Enhanced heat dissipation for fade resistance
• Reduced tendency to warp or judder under high thermal load
• Premium finish for quick bedding and consistent pad contact

Tech highlights

• Position: Rear axle
• Type: Vented rotor
• Diameter: 300 mm
