Why choose these 324 mm rear rotors for your BMW 135i cabrio

• Vented 324 mm rear fitment for the E88 135i cabriolet

• Ultra-precise finishing for excellent pad contact and reduced vibration
• Heat-treated castings for strength and durability under repeated heavy stops
• Direct replacement for the OE rear brake setup, no fuss fitment

Choose your preferred rotor style

• G88 – Multiple radial grooves promote airflow and heat dispersal to keep the system cooler and help prevent judder or cracking during demanding use.
• F2000 – Curved slots deglaze pads and balance cooling with structural integrity, ideal for hard road driving and regular track sessions.
• Sport Japan – Cross-drilled and grooved faces for maximum gas evacuation and bite, with countersunk holes to reduce the risk of stress risers. Great looks with serious performance.

Built to exceptional standards

• Castings based on OE specification and TUV approved
• Stress-relieved and heat treated after machining for dimensional stability
• Individually ground to achieve a near-mirror surface and superb pad bedding
• Tight tolerances target approximately 0.015 mm for smooth, quiet operation
