WAKE UP THE CHASSIS

Audi tuned your B10 S5 soft, but there is a great handling car waiting for a few suspension upgrades. Find it with an iE front sway bar that kills understeer and gives you the turn-in Audi forgot. Plus machined brackets with greasable zerk bushings for a performance upgrade that’ll last longer than the engine.

WAKE UP THE CHASSIS

THE BIGGEST FUN UPGRADE

Pound for pound, this bar is the single biggest change you can make to how the B10 S5 drives. It turns a heavy, safe cruiser into a car that begs for the next corner.

THE BIGGEST FUN UPGRADE

ENGINEERED FOR THE WEIGHT

We didn't reuse a B9 spec... we tuned torsion, flex and stiffness for the B10 S5's extra weight to ensure a dialed suspension that favors oversteer, sharper rotation, and honest feedback.

ENGINEERED FOR THE WEIGHT

FIT YOU CAN FEEL

Cheap bars are built to fit many cars and none precisely with sloppy mounts that dull the feel you paid for. iE sway bars are tailored for your B10 S5 alone, and it shows in every corner.

FAQs

Will this make my car harsh to drive?

No. A sway bar controls body roll in corners, not ride quality over bumps. You get sharper, more confident handling while your daily ride stays composed.

What's the real difference I'll feel?

The factory B10 understeers and feels heavy. This bar gives you crisp turn-in and a rear that rotates on command — the single biggest change you can make to how the car drives.

Do I need the front and rear together?

Yes, while the iE rear sway bar can be installed alone, the front iE sway bar requires a rear sway bar first. Start with a rear, and complete the set when you're ready.

Won't a stiffer bar wear my tires faster?

Just the opposite, sway bars help fix the geometry that can chew tires unevenly during aggressive driving. After iE sway bars, lowering springs, and wheel upgrades our B10 test cars all greatly improved not only grip and handling but also resulted in more even tire wear.
