You will have a bouncy ride just by the nature of the springs included with most coilovers. The stock shocks arent stiff enough to allow constant dampening during the up and down movements of a lowered car. You will blow them out in no time and end up basically riding on the springs. Trust me, ive been there. Unless you absoutely have your heart set on doing your suspension, sell your coilovers, and save up your money for that first kit i mentioned or something similar. You will thank yourself later. As im sure youve heard, or will hear soon enough. There is a saying that floats around the DSM camp. "Mod cheap, Mod Twice"
