To develop high performance threaded coil-overs for the street, Eibach relies on the experience gained from decades of involvement in racing at the international level — Formula 1, NASCAR, CART, IRL, Super Touring Car, World Rally Championship.

* Rust-free, stainless steel technology
* Extreme look that utilizes Formula 1 racing technology for the street
* Quick, adjustable lowering from 0.8" up to 3.0"
* Optimal damper tuning for aggressive performance

The technology behind Eibach's Pro-Street-S Coil-Over spring/damper kits is based on that used in the Eibach ERD Racing Dampers and ERS Racing Springs seen on race cars worldwide. Pro-Street-S Coil-Over kits feature rust-free, stainless steel struts and allow serious drivers the ability to quickly adjust the ride height and corner weight of each individual wheel, giving them the flexibility they demand for precise street and track tuning.
