I'm getting the KWs at a significantly cheaper price. An acquaintance of mine bought them new a few years ago for his ex Z4 3.0i, then he bought a Z4M and sold the 3.0i and never installed the KWs. He was selling them all this time but there was no interest in our small country so he lowered the price just to get rid of them
now that I suspect my shocks to be the reason for the front tyres rubbing I became interested in something better
