The Eibach Pro-System-Plus adds the final step for total suspension dominance. Pro-System-Plus kits are designed by their team of suspension engineers and ride control experts to offer the best-possible street performance, but without sacrificing ride quality. The Pro-System-Plus is a precisely balanced combination of sport springs, bump-stops (secondary springs), dampers and anti-roll bars designed and tuned to operate as a complete performance suspension system

Pro-System-Plus improves turn-in response, increases cornering speed and reduces body roll-all while retaining excellent ride quality. Pro-System-Plus is the ultimate street performance suspension system - a must for any true driving entusiast.

This is what Sport Compact Car said after road/track testing the AEM Ford Focus with Eibach Pro-System-Plus. "With the Eibach suspension, every last movement was damped out of existence...The Eibach suspension was confidence-inspiring in virtually any situation...(It's) one of the most well sorted aftermarket suspensions we've ever encountered"
