Why choose these rear rotors

• Size and type: 300 mm diameter, vented rear discs for efficient heat control
• Direct replacement: designed to fit the rear axle of BMW 1 Series E87 120d and 130i with OE calipers
• Heat treated and stress relieved castings for durability under repeated heavy stops
• CNC precision machining with an ultra-flat surface finish, runout tolerance approaching 0.015 mm for silky smooth braking
• Hand finished braking faces for consistent pad contact and reduced noise
• Excellent fade resistance and temperature stability during fast-road use

Choose your disc style

Pick the groove pattern that matches how you drive. All variants use OE-spec castings and carry recognised European approvals on many applications.

• G88 - Multiple fine radial grooves create a turbine-like effect that helps move heat and gases away from the braking surface. Ideal for drivers who want maximum cooling and a strong initial bite.
• F2000 - Curved slots that refresh the pad face and balance cooling with strength. A great choice for fast-road cars that also see the occasional track day.
• Sport Japan - Fully drilled and lightly grooved faces for aggressive looks and effective degassing to combat fade. One of the few options with genuine countersunk through-holes instead of dimples.

Best results with matched pads

Pair these discs with performance compound pads developed to work with heat-treated rotors for optimum bite, control and wear. Correct bedding-in will further enhance feel and longevity.
