Yes, going back to stock springs, but will be hopefully

using my Koni yellow sports with them. Now as we all know or should know, you need to trim your bump stops in half when installing lowering springs. So the question is, has anyone gone back to stock springs on aftermarket struts? Did you put in new bump stops? Leave them at the same length? How are polyurenthane bump stops? I really do not want to go down the poly path, but for the price they are pretty competitive.
