Description
For a 2019+ Audi RS5 (B9, RS5) | KW 253100CS being developed beyond stock suspension behavior, KW H.A.S. provides a more deliberate foundation for ride height, body control and tire management.
KW H.A.S. uses vehicle-specific springs and threaded height adjusters while retaining compatible factory dampers. It gives the owner a tunable stance rather than the single fixed drop of a conventional lowering spring, while preserving the OE damper architecture where the application is designed to do so. This makes it particularly useful when retaining compatible OE adaptive dampers or factory ride characteristics is part of the build objective.
Why Choose the KW H.A.S. for This Application?
Choose H.A.S. when you want adjustable ride height but do not want to replace compatible factory dampers. It is a more flexible stance solution than a fixed lowering spring and can preserve factory adaptive-damper functionality where KW specifies.

- Continuously adjustable spring-perch ride height

Enthusiast Setup Perspective
For mixed street and performance use, start from KW's baseline settings and make changes one variable at a time. That gives the driver a repeatable way to separate genuine setup improvement from simple changes in ride feel. For a road-driven car, preserving usable bump travel and sensible alignment is usually more important than using the full available lowering range.
