Ive never read that its a good idea to use stock shocks with any lowering springs.
Besides, even if you did it would be ok for a while.... until your stock shocks blow out quicker than usual. then you would have to replace them, as I said. thus spending two install prices vs the one.
youll save money in the long run. just my 2 cents. plus, your ride quality will be better with the koni shocks vs stock shocks. a lot better.
