Cars and trucks with performance specs are normally fitted with softer springs to allow for a comfortable ride. This is because manufacturers compromise to please the majority of their consumers that use the cars for everyday commuting and not for drivers that want to take the vehicle to its limits. The spring offers highest linearity in its class and guaranteed rate. It reduces tendency for the car body to lean over and also reduces body roll thus making the vehicle more stable with better handling and allows for faster cornering speeds.

The precision of the square end and plan-parallel configurations under loaded and unloaded conditions is to +/- 1 degree. The springs are individually rated and tested, it is made in the United States and they come covered by a million mile warranty. The warranty covers factory defects in materials and workmanship and it applies to the original purchaser of the product who still retains ownership of the vehicle in which the products were installed.

Eibach is a company that produces performance suspension for Formula One, NASCAR, WRC, CART, and so on. On occasion it has been said that they produce the finest performance suspension parts in the world. Eibach and its team of engineers develop products to meet the extreme demands required for any racing circuit. It is made with great precision which makes it very durable and ensures a reliable repeatable performance. When other springs sag and wear out, Eibach keeps on going. They know what professional drivers want from their vehicle, and they strive to create the best harmony possible between driver and vehicle on the road. Thus, drivers feel, lesser body rolls in hard cornering, reduced nose dive during braking, less squatting during acceleration, and a more direct handling with greater handling predictability.

Eibach has supported an uncountable number of race winners over the last 20 years from all genres of racing. This is due to the technology applied in making the product parts, from high strength spring steel alloy, to quality corrosion protection, and advanced CNC winding methods hence producing a products that are durable, reliable, and have optimum resistance to stress.
