Product Description

The PowerStop K2387 Z23 Evolution Sport Front & Rear Brake Kit is a complete 4-wheel brake upgrade for the 2002-2006 Acura RSX Base and 2004-2005 Honda Civic Si hatchback (EP3) - everything ships in one box. The Z23 Carbon-Fiber Ceramic pads deliver improved stopping power and significantly less dust than factory pads at both axles, while the drilled and slotted rotors keep brake temperatures in check for spirited driving and everyday use.

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 2004-2005 Civic Si EP3 only - the RSX Type-S uses a larger 300mm front rotor and requires a different kit. For a front-only Z23 upgrade, see PowerStop K2386.
