as we all have different preferences concerning harschness and handling it is really difficult to be able to help someone in their choice of springs and dampers.
a friend has field tested the same setup that i have only with 120pound springs and he found it way to soft for his taste. the original springs and setup on the beetle feels lika a ship on rough waters for me. no sense of control at all and i would rather have a harsch but controlled ride than a confortable one
