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.
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.

At Integrated Engineering (IE), we love to build, drive, create and innovate performance driven Volkswagen and Audis. We know first-hand the importance of quality designed, engineered, and reliable parts. That is why our team is dedicated to providing high-quality automotive performance products without compromising quality. We specialize in making your Audi or Volkswagen go faster for longer and stand behind all our products.
Our customers have grown to expect a quality build and finish that we strive to over deliver on, not only to manufacture the best, but to ensure the final product performs as well as it was engineered. This begins with an in-depth design process that can take months to years, and through specialized software, the digital product is designed and re-imagined many times over. From here, many products are "rapid prototyped" in ABS plastic to check dimension, fit, and in some cases application. Many of our high-power performance products such as connecting rods, camshafts, and valve train components undergo hours of ruthless testing on our in-house engine and chassis dyno facilities. This ensures that our products have real world-data, for real-world results, on real-world cars. At Integrated Engineering, we believe our commitment to bring you the highest quality performance products available with un-compromised performance truly sets us apart from the rest.
What began as two brothers, Peter & David Blais grew up with a shared passion for racing. That passion grew and Integrated Engineering was founded in 2007 in Salt Lake City, Utah. Since then, IE has set a new standard for performance products in many areas including connecting rods, camshafts, valve train, and billet accessories. Integrated Engineering has made a mark in the enthusiast community and continues to offer the quality and performance orientated product our customers demand. Our passion for the VW & Audi performance industry is clear, whether you interact with us on our website, phone, email, or online.
