If you are going to just use springs and not go the coilover route. Use the VWR springs. I put a set of Eibach springs on first and they just weren't matched to the dampers very well. Way too soft and bouncy over bumps. The VWR springs work WAY better with the stock dampers. It's still comfortable for a daily, but none of the bouncy that it had with the Eibach springs. It is literally night and day better.
