Description
The AST Suspension Adjustable Lowering Springs for BMW M5 (F90) offer ride-height adjustment while retaining the compatible factory dampers. This provides a way to set the vehicle stance without replacing the complete damper assembly.
Adjustable spring-seat hardware changes the installed spring position within the permitted range. Ride height and damping perform different jobs: spring-seat adjustment sets height, while the retained dampers control suspension movement. A lower setting is not automatically a better handling setting; clearance and available travel should guide the final setup.

Fitment and setup
Match the chassis, engine, drivetrain and electronic suspension equipment to the exact part number. EDC and Non-EDC versions must not be treated as interchangeable. Keep height adjustment within the application limits, then check alignment, wheel clearance and suspension travel. Retaining factory electronic dampers does not mean every model with that system shares the same spring kit.
