I have read everything in the archives about suspension and a fundamental question has not been answered. What is the advantage of going with coil-overs vs. new springs and shocks? I have a 98' M-Roadster that I want to lower a little bit and reduce the body roll some as well. It looks to me that new springs and shocks are in the $750 range and coil-overs are in the $1500. I would think labor would be about the same. comments/suggestions?
