GOODBYE, UNDERSTEER

Experience precision control, agility, and next-level turn-in feel on those aggressive corners, with the iE Adjustable Rear Sway Bar for your Audi. Engineered with a massive diameter spring steel and equipped with poly bushings for on-demand handling performance that does not compromise your daily driven comfort.

LEADING FEATURES

  • Reduced Body Roll -Body stays flat and stable through turns
  • Defeat Understeer -Corner faster and with more control
  • Adjustable Stiffness -Dial in your suspension feel
  • Increased Grip -Keep wheel contact with the ground
  • Teflon-lined Poly Bushings -Eliminates sloppy bushing flex


This rear sway bar must be paired with the matching iE Front Sway Bar

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.

AVERAGE INSTALL TIME: AROUND 1 HOUR

what a difference !
Note: there are no English instructions. I wanted this cleaning agent to disperse throughout the nooks and crannies of the engine, so about ten minutes before arriving at the mechanic's shop for my oil change appointment, I pulled the car over and poured this into the engine, then drove it the rest of the way there. The mechanic reported lots of sludge drained out with the oil. The engine seems to perform and sound better, as if it's not working as hard.

Buen producto
Buen producto, limpia perfectamente el motor interno y se libera la suciedad en el cambio de aceite. no use todo el contenido, creo que es bueno usarlo en 2 cambios de aceite para una mayor eficiencia.

Great will use it over and over again
I will use this in every car I own from now. Cleaned it real well did exactly what it said so and my truck runs a lot better definitely can tell the difference.. it was work the extra oil and work. The bottle I bought came with instructions in English, which made it easy for me. The quality of it is light brake cleaner, but meant for engines and it ran great very easy to use this pour in.

Does its job.
Always a go to before oil changes. Helps remove some extra sludge/deposits. DO NOT DRIVE OR REV THE VEHICLE WHEN USNG THE PRODUCT, only idle for 10-15 min. Ive seen reviews where people drove with it potentially ruining the engine.
