Subaru WRX Coilover Suspension Kit - Rear - Kartboy - Hard - `02-`07 is a rear suspension upgrade designed for 2002–2007 WRX models. This hard-spec rear kit tightens up rear compliance to provide a firmer, more connected feel for drivers who want clearer feedback from the back end.

Made for enthusiasts who want improved rear response for spirited street driving or occasional track use, this Kartboy rear kit focuses on reducing unwanted movement and improving load control during cornering. It installs using factory mounting points and is intended to pair with a variety of front suspension setups. The harder compound reduces deflection under load, helping the car react more predictably through transitions while remaining robust for regular use.
