Subaru WRX / STI 2015+. - One-Piece Race Spec Strut Tower Bar. Designed for the Impreza to decrease body roll, this bar ties the chassis from left to right at critical stress points (Between the shock/strut towers).
Mysubaru always had this weird chassis rolling feeling. Fixed it right up. So happy. Minor cutting of my truck liner but very worth it. Running front and back Megan strut bars.
