Description
The value of KW Street Comfort on a 2006–2013 BMW 3 Series (E90/E91/E92/E93 | RWD, Sedan, Coupe) is not just the change in stance; it is the ability to place the chassis in a more controlled operating window for the way the car is actually driven.
KW Street Comfort is aimed at drivers who want adjustable ride height and more disciplined chassis control without making maximum firmness the objective. Rebound adjustment lets the final setup be biased toward a more relaxed road ride or tighter body control as the vehicle and wheel/tire package demand. The application-specific calibration is intended to give the chassis a more deliberate response than a one-size-fits-all suspension combination.
Why Choose the KW Street Comfort for This Application?
Choose Street Comfort when road compliance remains a priority. It is aimed at owners who want a lower, more disciplined chassis but do not want a setup whose character is defined primarily by track use.

Enthusiast Setup Perspective
This setup makes the most sense when the suspension is being treated as part of a complete package. Final ride height, alignment, tire choice and available bump travel should be considered together rather than setting the car as low as possible. For a road-driven car, preserving usable bump travel and sensible alignment is usually more important than using the full available lowering range.
