Description
The Kartboy Rear Shifter Bushing is one of the best upgrades you can make to sharpen the driving experience of your WRX or STI. The OEM rubber bushing allows excessive movement in the shifter stay, which results in slop and vagueness during gear changes. Kartboy eliminates this with a CNC-machined, high-durometer polyurethane bushing engineered to lock the shifter stay firmly in place.
Installation is straightforward and produces an immediate, noticeable difference—tighter, cleaner shifts with improved driver feedback. Whether daily driving or carving corners, this bushing helps your Subaru feel more precise and focused.
