As long as your drop isn't more than 1.5" (and I don't think it will be with those springs) then you should be able to avoid using c/c plates. Regarding those bolts, I've heard/read bad things relating to safety concerns over those things, so maybe steer clear. If I can remember where I read such info on those bolts, I'll come back and post a link.
