Product Description

ASTALS-21-004 replaces the factory springs on the listed BMW G87 M2, G80 / G81 M3 and G82 / G83 M4 applications, adding ride-height adjustment while retaining the original dampers. The spring platforms allow the installed height to be reset within the permitted range for the vehicle.

The kit retains the factory damping system, including electronic damper control where fitted. Set the height with suspension travel and wheel and tyre clearance in mind, then check alignment at the final setting.

FAQs

Does this kit include replacement dampers?

No. The spring and height-adjustment system is used with the specified original dampers.

Does the electronic damper system need coding out?

No. On a correctly matched electronic-damper application, the original dampers and their electronic controls are retained. This differs from a non-electronic coilover conversion.

What needs checking when setting the height?

The setting must remain within the limits for the exact application. Check suspension travel, wheel and tyre clearance and alignment at the chosen ride height.
