wrong. For the front, being a macphearson strut design, has a 1:1 ratio in relation for the lca moving 1" and the shock compressing 1", so you could almost assume it does not affect other suspension components. The problem is more apparent in a multilink suspension such as the rear links on our car. It's difficult to conceptually visualize, but a few hardcore racing companies have developed new spindles in contrast to addig spacers under the lca to combat the negative affects of lowering a production based vehicle while preserving the initial suspension dynamics from the factory. In other words there more to adding spacers between the knuckle and lca.
