This kit is designed to lock the front of the rear diff support outriggers where they mount to the body. It will suit both early (94-00) and later (MY01, 2002) models of Subaru Impreza, WRX and STi.

Fitting of the kit will reduce rear-end float particularly under acceleration. It will also remove drive train “thump!!!” on hard gear changes while delivering more precise handling and chassis response. It will INCREASE NVH .
