THE PERFECT BALANCE
The iE rear sway bar’s massive 22mm outer diameter achieves the ideal balance between optimum performance in the twisties and a comfortable daily ride. This ideal diameter size, combined with iE’s one-piece spring steel design, increases stiffness to deliver maximum control in the turns. Maintain a smooth and comfortable ride, along with the rush of “vigorous” driving, without adding excessive vibrations or harshness.
CORNER CONFIDENCE
For navigating winding roads or pushing the limits on the track, the iE rear sway bar delivers greater control and stability. Maximize grip at the rear wheels and reduce body roll during cornering. Rotate more efficiently through corners with less understeer.
ADJUSTABLE STIFFNESS
User-adjustable stiffness settings allow you to dial in your perfect handling feel. The rear mounting position provides a softer feel, with a 150% increase in stiffness over the stock sway bar. An even more aggressive and responsive experience can be achieved with the front mounting hole, resulting in an impressive 205% increase in stiffness.
LIGHTWEIGHT ADVANTAGE
With its robust, 6.5mm wall thickness, iE’s rear sway bar maintains strength and agility while controlling body roll. Although it is lightweight, this sway bar boasts high strength to distribute forces without risking breakage or bending, even in the most demanding driving scenarios.
NO SLOP, NO NOISE
iE polyurethane bushings have been designed to eliminate the "sloppy" feel of the stock rubber bushings. They significantly reduce bushing flex between the sway bar and chassis, resulting in a tighter suspension feel. A durable, Teflon coating applied to the bushing keeps your sway bar operating squeak-free.
INSTALLATION
Your new sway bar is a simple, direct bolt-in replacement. No adjustments or special tools are required. For maximum handling, install the iE Sway Bar End Links with your iE Rear Sway Bar.
