Your Audi deserves better than the 'lifted' factory look. iE obsessed over the measurements to calculate a drop that doesn't just lower the car, it corrects it. By eliminating the factory reverse rake, iE has achieved a flush, aggressive fender-to-tire fitment that looks right while retaining functional clearance for real-world driving.
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.
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.
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.
SET AND FORGET
These springs are built for owners who drive their cars. Engineered to work seamlessly with OEM dampers, Chrome Silicon alloy construction ensures sag-free, consistent performance for the long haul.
