Product Description

The PowerStop K2386 Z23 Evolution Sport Front Brake Kit is a front brake upgrade for the 2002-2006 Acura RSX Base and 2004-2005 Honda Civic Si hatchback (EP3). The Z23 Carbon-Fiber Ceramic pads deliver improved stopping power and significantly less dust than factory pads, and the drilled and slotted vented front rotors keep brake temperatures in check during spirited driving and canyon runs.

G3000 grade iron rotors are precision-cast to OE tolerances for a direct bolt-on fit with no modifications. This kit is for the RSX Base and Civic Si EP3 only - the RSX Type-S uses a larger 300mm front rotor and requires a different kit. For a complete front and rear upgrade on the RSX Base or Civic Si, pair with the PowerStop K2387 or K2391.
