Eibach Pro-Tronic – BMW 1/2/3/4/X3/X4

Eibach's range here is built around the coil spring. Pro-Kit is the main lowering spring, with Sportline and SportlinePLUS for a lower stance, and the ERL Replacement Line supplies OE-height springs for cars whose original springs have sagged. Around the springs sit B12 Pro-Kit and B12 Sportline spring-and-damper kits, Pro-Street-S height-adjustable coilovers and Pro-Spacer wheel spacers. Then come Pro-Lift-Kit raising springs, Pro-Tronic kits for cars with electronically controlled dampers, and anti-roll bar kits, some with two or three settings.

Most of the range is listed for European cars. Volkswagen, Audi, BMW, Mercedes-Benz, Skoda and Seat lead, followed by Opel, Ford, Renault, Peugeot, Fiat and Volvo. The Audi A3, Volkswagen Golf, Skoda Octavia and Seat Leon come up most often.

Compared with the other spring brands here, Eibach covers the spring in every direction: lowered, factory height and raised. If you are after a wide choice of adjustable coilovers, you will find more lines elsewhere in the Coilovers section. Eibach's focus is the spring and the parts built around it.
