BMW E88 120d Cabriolet Rear Rotor Upgrade 300 mm Vented

Enhance the stopping performance of your BMW 1 Series cabriolet E88 120d with premium rear rotors from Tarox. Engineered for fast road and spirited driving, these 300 mm vented back-axle rotors deliver confident braking, excellent heat management and superb pedal feel. Trusted by enthusiasts and used by our own team, this is a serious upgrade for anyone wanting sharper response, fade resistance and a quality OE-spec replacement that looks as good as it performs.

Why choose this rear rotor upgrade

• 300 mm diameter vented construction for improved cooling under heavy use
• Heat treated for strength and durability during high temperature cycles
• Precision CNC machining and meticulous hand finishing for ultra-smooth braking
• Surface ground to an exceptionally tight tolerance for minimal runout and reduced vibration
• Based on OE specification castings with TUV-approved quality

Proven Tarox designs to suit your driving

• G88 - Multiple radial grooves create a turbine effect that moves hot gases away from the pad, helping the rotor run cooler and reducing the risk of judder and cracking.
• F2000 - Curved grooves deglaze pads and balance heat dissipation with strength, ideal for fast road and track-day use.
• Sport Japan - Fully drilled countersunk holes combined with six grooves for aggressive bite and effective gas evacuation to combat fade.

All options are produced from OE-spec castings, heat treated, and individually finished by skilled operators for that signature bright, smooth surface. Pair with Tarox pads for optimum bite, consistency and feel.
