THE FIRST STEP IN SUSPENSION PERFORMANCE
Eibach PRO-KIT is the perfect answer for most frequently-driven street cars. It's our legendary spring system that dramatically improves both a vehicle's performance and appearance.
PRO-KIT lowers your GT'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.

By using our proprietary, progressive spring design, PRO-KIT provides the ultimate balance to take your passion for driving to a whole new level.
