Eibach Pro Kit Springs

Part #: 4031.140

Most people install the legendary Eibach PRO-KIT Spring Set for the obvious performance benefits: sharper cornering, increased steering precision, reduced brake dive and that lower, leaner look.

But as Eibach proved in the latest in a series of scientifically rigorous mileage tests, the 2011 Civic Si also gained an impressive 7.5% in highway mpg, improving its efficiency from 31.98 mpg to an amazing 34.38 mpg. To put that in perspective, that 7.5% increase would result in a $330-dollar savings over 50,000 miles (assuming a $3.00-per-gallon average gas price). Which means that the Eibach PRO-KIT springs will more than pay for themselves in the first 50,000 miles—and then, considering Eibach’s Million-Mile Warranty, will keep on saving for many years to come.

The lower stance of the Eibach-equipped Civic decreases the frontal area of the already-streamlined machine, and reduces turbulence under the chassis which also adds to aerodynamic drag. This mileage testing was done under strictly controlled conditions, at a constant cruise-controlled speed, starting at 5 A.M. on a consecutive Saturday and Sunday to eliminate traffic, wind and weather factors. The only modification made to the test-subject Civic was the installation of the Eibach PRO-KIT Springs.
