Product Description

The Hawk HB604F.598 HPS rear brake pads are engineered for the rear axle of the 2008-2013 BMW 135i (E82 coupe and E88 convertible) and 2013 BMW 135is - the turbocharged 3.0L six-cylinder variants of BMW's 1-Series platform. Paired with the HB603G.616 DTC-60 front pads for track use, or the HB603F.616 HPS fronts for street, these rear pads round out a well-matched braking upgrade for the 135i's balanced chassis. For daily-driven 135i owners who want improved stopping confidence over factory pads without adding noise or dust, the HPS compound is the straightforward choice.

The HPS delivers 20-40% more stopping power than standard replacement pads, with smooth initial bite and a wide operating range that works from cold on the morning commute through spirited weekend driving. These rear pads also fit E9X Performance BBK rear configurations using the same caliper interface - verify your specific BBK spec before ordering. A proper bed-in procedure is recommended after installation to achieve optimal performance.
