The Eibach PRO-PLUS handling packages include our legendary Eibach PRO-KIT springs along with the matching ANTI-ROLL-KIT Sway Bars. The Eibach PRO-KIT lowers your car's center of gravity, reducing squat during acceleration, body roll in corners and excessive nose-dive under braking. Add the Eibach ANTI-ROLL-KIT Sway Bars - with increased design stiffness over stock Sway Bars - and you get pure, balanced-handling perfection. With the Eibach PRO-PLUS installed you will immediately experience precise turn-in response, improved handling and cornering grip - in any performance-driving situation. The Eibach PRO-PLUS works well with both factory or aftermarket performance dampers and shock absorbers. * Your results may vary. As we have learned from racing and independent testing has proved - lowering your car or truck's ride height also improves your aerodynamic efficiency by forcing more air over the car and less underneath (where most of the drag is found on any vehicle), resulting in higher top speeds on the track and better MPG on the highway.
