Engineered to 'Activate More Grip', sway bars are principally designed to reduce body roll or sway. By reducing body roll, lateral loads are spread more evenly across the tires thereby increasing cornering grip and improving outright performance.
Whiteline's 22mm 2-point adjustable Rear Sway Bar is one of the best modifications you can do to improve your 10th Gen Civic's handling! Having tested it personally on Street and Track with a stock front sway bar in place still, I felt that the rear wanted to rotate with the front of the car, and not just dragging around like a dog's tail. The Unity Si was more eager to turn in, but at no point felt scary that it would oversteer out of control. In fact, benefits extend to improvements in handling, safety and tire wear without affecting ride quality or comfort. See attached pictures of 18mm Si vs. 22mm Whiteline rear sway bar.
The Unity Si will soon be equipped with the Whiteline Front (27mm) Sway Bar, so "handling like it's on rails" will be an understatement!
Mounting Polyurethane Bracked included, and Grease is included. Stock sway bar links are compatible; Whiteline rear sway bar links can be purchased separately.
