THE SCIENCE OF STANCE.

Your Audi deserves better than the 'lifted' factory look. We obsessed over the measurements to calculate a drop that doesn't just lower the car, it corrects it. By eliminating the factory reverse rake, we’ve achieved a flush, aggressive fender-to-tire fitment that looks right while retaining functional clearance for real-world driving.

THE SCIENCE OF STANCE.

STAY FLAT. STAY STUCK.

Body roll is the enemy of grip. iE Performance Springs use carefully tuned rates that keep the chassis flat and composed through high-G corners, keeping the car glued to the pavement.

STAY FLAT. STAY STUCK.

GOODBYE, UNDERSTEER.

You’ll feel it in the very first turn. By rebalancing the front-to-rear spring rates, we sharpened turn-in and dialed down the understeer. Squat is minimized. Dive is controlled. The car simply goes where you point it, instantly.

GOODBYE, UNDERSTEER.

PROGRESSIVE PERFECTION

Performance shouldn’t punish you. Our progressive rate design remains compliant over road imperfections, then ramps stiffness under load. The result is confident body control without the bounce, crash, or harshness of poorly designed springs.

PROGRESSIVE PERFECTION

Frequently Asked Questions

1. Will these Audi B9 lowering springs work with my factory shocks?

Yes, IE springs are specifically calibrated to function with the stock B9 dampers, ensuring long damper life.

2. Do these B9 lowering springs affect Adaptive Suspension modes?

No. The springs are fully compatible with Audi Drive Select. Comfort mode remains compliant, while Dynamic mode becomes even sharper.

3. How aggressive is the drop on Audi B9 models?

Balanced and intentional. The ride height eliminates factory wheel gap and reverse rake without looking slammed or compromising daily usability.

4. Is this a performance spring or a cosmetic spring?

Performance. While we 'nailed the look,' the primary goal was chassis dynamics. The 55CrSi steel and increased spring rates are designed to reduce body roll, stop nose-dive during braking, and sharpen steering response.

5. Is the ride stiff?

It is firmer than stock, as intended for a performance application. However, the Progressive Rate design prevents it from being 'crashy.' You get a connected, sporty feel that communicates what the car is doing.
