I've got STP on my car but I still want to lower my center of gravity a little more. Has anyone run KW V2s or Pedders for a few years? I'd like to know how they hold up overtime. The Pedder's look ok but the KWs look like they would last a lot longer against corrosion from moisture. One of these seems like the best option south of $2k but if their trash I'll just get some Vogtland springs.
