Description

The COBB Rear Sway Bar is a 24mm, 3-position adjustable sway bar engineered to enhance the handling dynamics of your Subaru WRX and STI. Constructed from hollow steel, it offers a superior stiffness-to-weight ratio compared to solid bars. The adjustable end positions allow for fine-tuning of the vehicle's handling balance; moving the attachment point closer to the center reduces stiffness, while moving it further out increases it. This enables drivers to tune the roll stiffness for different driving situations without replacing the entire bar. Polyurethane mounting bushings are included for effective vibration damping and durability. Please note that end links are sold separately or may be included in a complete package. This sway bar is compatible with 2015-2021 Subaru WRX (FA20DIT engine) and 2015-2021 Subaru WRX STI (EJ257 engine).
