BMR's suspension designed the SB012 sway bar for street performance, autocross, and road race applications. The large adjustable sway bars three positions give you the versatility to drive to and from the road course or autocross and still out handle the competition with the same sway bar. The SB012 front sway bar gives you a 87%-137% increase in sway bar rate. These rate increases and adjustability allow you to fine-tune the handling characteristics of your Mustang so you can drive harder through corners with minimal body roll. The hollow design allows for loads of strength in the lightest package possible. This means increased performance with no sacrifices. The SB012 attaches to your G8 with 88-durometer polyurethane bushings, reducing the deflection from the stock rubber bushings. This allows for more sway bar control, and more control equals better handling.
