The Eibach Pro-Kit is the perfect answer for most frequently-driven street cars. It's Eibach's legendary spring system that dramatically improves both a vehicle's performance and appearance.

Pro-Kit lowers your car's center of gravity, reducing squat during acceleration, body roll in corners and excessive nose-dive under braking. When combined with Plus-1 or Plus-2 wheels and tires, the Eibach Pro-Kit is the finishing touch to a winning recipe for performance. Pro-Kit also reduces excessive fender-well clearance, making your car look just as hot as it performs.

Every Eibach Pro-Kit is designed and tested by Eibach's suspension engineers and performance driving professionals, to deliver aggressive good looks and high performance handling, without ever compromising safety or ride quality. By using Eibach's proprietary, progressive spring design, Pro-Kit provides the ultimate balance to take your passion for driving to a whole new level.

Greatness wrapped in a Box

The pro kit has given my cobalt tremendous ride quality. The drop is not noticeable at first but the springs will settle in around four months. In the meantime, you can enjoy the smooth gear shifts, low wheel noise, great spring rate, and a more even look to your car. I drive a standard and with these springs, there is no "dip" and "dive" when shifting gears (especially from 1st to 2nd - the LT and LS is known for the front dip). These are a great buy and if you have never drove a car with performance springs, after these springs you will want one in every car you sit in. Great quality with a life time Warranty.. What can you ask for? 5 out of 5 stars from my end.
