INSTALLATION INFORMATION

Assembly

We recommend that our lowering springs be installed by a specialist workshop having the experts and special tools. Prior to assembly, it is absolutely necessary to read the TUV expertise comparing it with the data of the car and the delivered chassis part in order to exclude future assembly and technical problems concerning the TUV.

Brake Power Regulator

If the vehicle is equipped with a load-dependent brake power regulator on the rear axle, we recommend checking this regulator and having it re-adjusted by your specialist workshop.

ABS

Vehicles equipped with an anti-blocking system: the sensors have to be accurately re-adjusted after mounting our lowering springs.

Level Adjustment

Vehicles equipped with level adjustment: requires re-adjustment after mounting our lowering springs.

Wheel Adjustment

After our lowering springs are installed, wheel adjustment values must be checked.

Measuring Method

The lowering indicated by us results from the difference between the standard ride-height (distance between fender and the center of the wheel) and the ride-height after lowering. You should take into consideration that in case of lowering carried out by the factory, the dimensions are reduced by this lowerage.
