PSI is proud to begin offering the new KW Suspension Height Adjustable Spring (H.A.S.) System for the BMW F80 M3 and F82 M4! Those of you who have been looking for a solution that allows you to adjust your ride height while retaining the OEM EDC capability – your time is now.

KW Suspension is a household name today in the world of street and competition suspension systems, and rightly so. Their reputation and quality speaks for itself. The new H.A.S. for the M3 and M4 utilizes front and rear KW progressive-rate springs with threaded height adjusters. Your existing OEM shock absorbers remain in place, allowing all electronic controls to continue unchanged.

The true beauty of this setup, in our view, is the infinite height adjustment afforded by the threaded sleeves, allowing you to pursue that perfect stance while allowing the EDC to function uninhibited. We here at PSI fully support KW products for the M3/M4, as befitting a world-class sports car platform.

Weight: approx. 40 pounds.
