Description
KW V2 Coilovers – 2007–2009 Mazda 3 MPS-Mazdaspeed (BK) is built for the enthusiast who wants the suspension to become a functional part of the chassis setup, not simply a visual drop.
KW V2 adds low-speed rebound adjustment to the core KW street coilover concept. KW's current V2 technology uses a 16-click rebound adjuster, allowing the driver to influence how firmly the chassis is supported as the suspension extends after a compression event. 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 V2 for This Application?
Choose the V2 when ride height alone is not enough and you want direct control over rebound. Rebound tuning can be used to influence how quickly the chassis settles after compression and how firmly the body is tied down through transitions.

Enthusiast Setup Perspective
The tuning opportunity is greatest when the car has already moved beyond basic cosmetic modification. As grip and braking capability increase, damper control becomes progressively more important to keeping the chassis predictable. For a road-driven car, preserving usable bump travel and sensible alignment is usually more important than using the full available lowering range.
