BMR Suspension designed the SB004 sway bar for street performance, autocross, and road race applications. The SB004 gives you a 200% increase in rate over the stock bar. These rate increases allow you to drive harder through corners with minimal body roll. The hollow design allows for loads of strength without adding a lot of weight. This allows for more sway bar control, which equals better handling. When performance is a must, rely on BMR Suspension.
