OVERVIEW
The KW Street Comfort kit is an individually adjustable sport suspension built around maximum comfort. Height adjustment allows a lowering of roughly 10–40 mm depending on the vehicle, which gives you the flexibility to set the stance you want and to clear aftermarket wheel and tire packages.
The moderate drop also has a positive effect on driving dynamics and road contact. Because the lowering is discreet, more suspension travel is retained, and the comfort-oriented springs are matched to harmonically tuned dampers so ride quality stays the priority.
