Whiteline Subframe Lock Kit

The Whiteline Subframe Lock kit is designed to lock the rear subframe on the Impreza, WRX and STi models. It allows for more precise alignment of the rear wheels and limits the amount of rear subframe movement under cornering loads, which can result in poor dynamic alignment settings. Simply insert and tighten, for race days to lock the rear Subframe in place for increased performance.
