Part Type

Coil Spring Lowering Kit / Stabilizer Bar Kit

Product Overview

If you live for the corners, the Eibach SPORT-PLUS Performance Handling Package delivers. Eibach SPORT-PLUS packages include our legendary Eibach SPORTLINE springs along with matching ANTI–ROLL–KIT sway bars. The Eibach SPORTLINE 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 roll stiffness, compared to stock bars –and you get pure, balanced–handling perfection.

With the Eibach SPORT-PLUS installed you will immediately experience more-precise turn-in response, improved handling, and enhanced cornering grip in any performance-driving situation. The Eibach SPORT-PLUS is designed and tested to work well with either factory or aftermarket performance dampers.

*Features*
• The Same as PRO-PLUS – Just More Aggressive
• SPORTLINE + ANTI-ROLL-KIT = SPORT-PLUS Performance Handling Package.
• Extreme-Performance Springs and Sway Bars = Race-Car Like Handling for the Extreme Enthusiast
• Similar to the Eibach PRO-PLUS Performance Handling Package, the SPORT-PLUS, with our SPORTLINE spring kit, sits lower and will deliver the precise turn-in response, improved handling and intense cornering grip every serious enthusiast craves.
• Your results may vary. As we have learned from racing and independent testing, 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.
