Overview

It features a diffuser design that replaces the stock rear under panel, aiming to enhance the car's rear aesthetics by creating a wider appearance and a more streamlined look.
Show original supplier description
The C-West Rear Half Spoiler is crafted from PFRP (Plastic Fiber Reinforced Plastic) and is designed to enhance the sporty appearance of the Honda CR-Z ZF1 and ZF2 models. It replaces the factory rear underbody panel with a more aggressive diffuser design, contributing to a wider and sleeker rear-end look. This aerodynamic enhancement also serves a functional purpose by helping to vent heat from the rear wheel wells, achieved through modifications to the inner liner. The original factory tow hook can still be utilized with this spoiler installed. Please note that the demo car in promotional images features a custom two-tone paint scheme, and this product is sold unpainted.
