The customer came to us looking for a solid set of coilovers, he was looking at a set of STs, or a set of KWs; needless to say he was already on the right path! Since the V1s and STs both come with factory pre-set dampening to help you get the best ride, the choice was ultimately between materials used and the warranty behind the product. After some consideration he decided on the KW V1s for their top shelf quality, and 5 year warranty.
