Installation Care
We have put together a few notes for you to consider.
Lowering & height amounts
All Lowering amounts are provided from a standard height car, if you have a lowered vehicle or sports model then the lowering amount may differ.
Alignment
Wheel adjustment - after completion of the spring/suspension installation, checking the wheel adjustment is required. If you are setting up the car for any specific use, for example racing for a fast road set up then please contact a tuner for best advice, however Eibach would reccomend putting all alignment back to OE specification.
Which damper
Eibach Pro-Kit springs are designed to work with OE shock absorbers but do check the damper upon installation of the springs for any signs of wear and should be changed when needed.
The installation of sport dampers can improve your suspension set up with Eibach's lowering springs for example example Bilstein B8
