About Eibach

History and information about Eibach and their products.

The people at Eibach and LMPerformance know that the performance driver wants immediate response, reduced body roll, increased stability, enhanced cornering ability and a lower, more muscular look in their vehicle. But did you know that installing aftermarket springs can result in better fuel economy. Aftermarket springs are generally lower and Eibach's Pro-kit springs are typically one inch lower than its original parts. When you install this kit the body ends up riding lower on the wheels. Lowering the body reduces the frontal area of the vehicle which, when multiplied by the drag coefficient, reduces the total drag for the vehicle. This can result in greater fuel efficiency. An unexpected bonus at today's fuel costs.

Why choose springs from Eibach? Eibach is one of the leading manufacturers of aftermarket suspension components and uses high-strength spring-steel alloys, an advanced CNC winding process, and offers high-quality corrosion protection. The Eibach engineers tune the individual components to provide more direct handling and greater predictability. Eibach has a Quality Control System that is certified by the highest ISO 9001:2000 international quality standard and operates in accordance to its own, often more rigid, specifications.

LMPerformance can help get the performance you want with the added bonus of fuel economy with aftermarket springs from Eibach. LMPerformance carries a wide selection of Eibach parts, including Eibach springs, Eibach Coil over kits, Eibach shocks, Eibach suspension kits, Eibach swaybars and Eibach wheels for your car and , of course, a great price.

Meeting the severe demands of the performance driver is the primary goal at EIBACH and to this end EIBACH employs engineers who can do just that and as a consequence they are known throughout the world for their dedication to technology and innovative designs in the suspension products industry. EIBACH started as a family owned business in 1951 and remains that even today with plants, engineering and sales divisions spanning the globe with an extensive array of products to their credit and a marketplace in over eighty countries. While the EIBACH name is renowned in the racing industry the EIBACH goal is not just to supply those enthusiasts with primo suspension products but also to satisfy the performance driver like you who wants a more aerodynamic look and better handling car because they know that success in the industry is dependent on designing and manufacturing a quality suspension product for a multiplicity of vehicles and driving situations. While the original design of a car’s chassis may be satisfactory for the everyday driver, the performance driver wants more from their car and the EIBACH team is in a position to give them what they want because of their years of experience in the field and their choice of employees who have the knowledge and capability needed to design and manufacture a superlative aftermarket suspension product. EIBACH didn’t neglect you SUV and truck owners but designed parts like the CADILLAC Escalade 2007 - 2011 SUV PRO-KIT on the LMPERFORAMANCE web site that is designed to lower your SUV affording you better handling and a reduced chance of rollover something that is particularly true for SUV’s because according to the US National Highway Traffic Safety Administration these vehicles have between a fourteen and twenty-three percent chance of rollover compared to the ten percent chance in a car. To even further enhance your SUV or truck like the iconic Ford F-150 so popular on the road today, EIBACH designed the PRO-DAMPERS also available on the LMPERFORMANCE web site that will augment the PRO-KITS for these vehicles by helping to control spring oscillation and consequently improve the overall performance of the suspension system.

Eibach FORD Taurus SHO 3.5L V6 EcoBoost AWD 2010 - 2011 PRO-KIT Performance Springs (Set of 4)

Ownership: 1 week - 1 month
I was debating between H&R and the Eibach springs. I am glad I went with the Eibach. It lowered the vehicle nicely without being too low; just perfect. Ride seem a tad stiffer (as expected) but did not adversely affect the ride quality (car came with the Sports Package).

Stock - fresh off the factory floor.

This part has made the Camaro and fun ride and much more stable. For less than $500 installed this is a must fix for this car. Now I feel comfortable taking it to the track. I suggest this if you want to push the car around corners safely.
