I'm removing the Lakewoods and swapping in some MM coilovers/Bilsteins. These are for a drag setup and not really good for a street car. They are almost new. Maybe 200 or so miles since installed. The car came with them alresdy installed from a new build. Not sure about the spring weight. I'm fairly sure it's the coilovers that come with the Team Z Matrix K-member. $150 + whatever shipping costs.
